Column: Two Rutgers professors are accused of poisoning the debate over COVID's origins. Here's why
In a Dec. 2 tweet, Richard H. Ebright, a professor of chemistry and chemical biology at Rutgers University, stated that Anthony Fauci, the respected virologist and retired official of the National Institutes of Health, “is likely a murderer and provably a felon.”
In another tweet a few weeks earlier, he had compared Fauci to the Cambodian dictator Pol Pot, who was responsible for the genocidal massacre of as many as 2 million people in the 1970s.
Referring to an event at Case Western Reserve University honoring Fauci, Ebright wrote: “You may have missed the chance to hobnob with Pol Pot, but, Case Western will give you the chance to hobnob with Fauci, whose policy violations … likely killed 20 million.”
Every time I speak publicly, I now have a thought that there might be someone who has ingested this steady stream of distortions who might shoot me while I’m speaking.
— Michael Worobey, University of Arizona
In a tweet Aug. 25, 2022, Ebright’s colleague Bryce Nickels, a professor in the Rutgers department of genetics, called the “coordination” among virology researchers including Angela Rasmussen of the University of Saskatchewan and Michael Worobey of the University of Arizona an example of “pure, unfiltered evil.”
He illustrated the tweet with a GIF from the 1976 movie “Marathon Man” showing Dustin Hoffman being tortured by a character played by Lawrence Olivier and plainly inspired by Nazi doctor Josef Mengele.
This is the landscape on which a conflict over two theories about the origin of COVID-19 has been waged. One theory attributes the origin to unregulated trading in China of disease-susceptible wildlife, from which the virus that causes the disease is thought to have leaped to humans in a process known as a zoonotic spillover.
The other, the lab leak hypothesis, posits that the virus escaped from a virology lab in Wuhan, China, where it may have been deliberately concocted.
Let’s be clear: There is no evidence for a lab leak. No one has ever produced anything in its favor other than innuendo and conjecture. By contrast, evidence for a zoonotic transfer is almost overwhelming, has grown ever stronger over the years and is widely accepted by virologists and epidemiologists.
Ebright and Nickels are advocates of the lab-leak theory. For years they have been posting online insinuations or outright accusations of fraud, perjury, felonies and murder aimed at scientists who advocate for the zoonotic transfer theory.
Now a dozen scientists, some of whom have been direct targets of Ebright and Nickels, have called on Rutgers to open a formal investigation into whether its two faculty members have crossed the line distinguishing between responsible scientific debate and defamation, harassment, intimidation and threats.
Among the concerns the signatories aired in their March 14 complaint letter is that the professors’ actions and “inflammatory language,” such as “comparisons of working scientists to historical war criminals and mass murderers,” could “put some of us and … our colleagues in physical danger.”
Ebright’s and Nickels’ behavior, the complaint says, has unfolded in an atmosphere that had already produced “harassment including threats of death and/or violence because of our … scientific research.”
Ebright and Nickels say the complaint misrepresents their words and activities. “I never have compared any of the signatories to Josef Mengele or Pol Pot, and I never have characterized any of the signatories as murderers,” Ebright told me by email. He adds, “I also never have threatened or incited violence against any of the signatories.”
He did acknowledge calling four signatories “fraudsters,” based on their authorship of a 2020 scientific paper that favored zoonosis as the origin of COVID-19 and dismissed the lab-leak theory as implausible. “I stand by this characterization,” he wrote. He called the complaint “an effort to silence opponents and to prop up a collapsing narrative.”
Nickels told me by email, “the assertion that I have labeled any of the 12 signatories as murderers or endangered them or their colleagues is false and is defamatory with malice.” In his email, he accused the same four signatories mentioned by Ebright of fraud.
More on that shortly.
The complaint letter says that Ebright and Nickels have engaged in online harassment, intimidation and threats for years. According to Kristian Andersen, an evolutionary biologist at Scripps Research in La Jolla and the organizer of the complaint, a new element in their approach recently appeared: encouraging their followers to engage in physical contact with zoonosis advocates.
On March 12, Nickels tweeted a notice of a scientific conference in Washington at which Peter Daszak, the head of a research funding organization who has long been the target of vituperation by lab-leak advocates, would appear on a panel.
“Don’t miss your chance to meet Peter Daszak, author of the grant many consider the ‘Blueprint’ for SARS-CoV2!” he wrote. The reference was to a groundless accusation beloved by lab-leak advocates that a grant proposal sponsored by Daszak’s organization involved creating a virus in a Chinese lab that became SARS-CoV-2, the virus that causes COVID. Virologists say the grant proposal would not have produced such a virus. In any event, it was not funded.
“That was so far outside of what I would consider to be normal and ethical conduct in science that I said, we need to file a formal complaint,” Andersen told me. The scientists’ letter to Rutgers administrators doesn’t ask for any disciplinary action, but calls for “immediate and serious review by the administration” of public behavior by Ebright and Nickels.
The call by Ebright and Nickels for followers to show up at a talk by Daszak stepped up the anxiety many scientists feel about their own public appearances.
“Every time I speak publicly, I now have a thought that there might be someone who has ingested this steady stream of distortions who might shoot me while I’m speaking,” says Worobey, a signatory of the complaint whose research helped to establish a seafood and wildlife market in Wuhan, not a lab, as the likely site of the first zoonosis transfers. “With those escalations recently, I thought it was time to deal with it head-on.”
Vaccine science, immigration and elections are all battlegrounds for the war between information and disinformation today. The temperature of debates on these topics is only heightened by the tendency of social media platforms such as Twitter (now X) to encourage intemperate speech. But science and health seem to be areas especially vulnerable to efforts at falsification.
A brief primer on the lab-leak hypothesis may be useful here. During the earliest weeks of the COVID pandemic, many virologists examining the SARS-CoV-2 virus, including Andersen, spotted unfamiliar features, some so unusual that they conjectured the features might have been man-made.
Further research in the ensuing weeks revealed, however, that these features were not unusual, but common, and that they could develop in viruses such as SARS2 through natural processes. Andersen and others eventually concluded that a laboratory role in COVID’s emergence was implausible.
That conclusion was written into a seminal paper on the virus published in Nature Medicine on March 17, 2020, and titled “The proximal origin of SARS-CoV-2.” Its authors included Andersen, Robert F. Garry of Tulane University, Andrew Rambaut of the University of Edinburgh and Edward C. Holmes of the University of Sydney.
All four signed the complaint letter to Rutgers. They’re the four scientists Ebright and Nickels accused of fraud in their emails to me, based on the Rutgers scientists’ claim that the proximal origin paper was fashioned to serve what Ebright and Nickels assert was the authors’ and Fauci’s desire to downplay
Fauci’s role in funding virology research in China.
Ebright further accused Andersen and Garry of perjury, based on their denials at a congressional hearing in July that Fauci pressured them to advocate for the zoonosis theory in their paper.
After the paper’s publication, the lab-leak hypothesis moved into the partisan political realm. Republicans in Congress cherish the notion that Andersen and his colleagues deliberately minimized a laboratory role at Fauci’s behest.
There is not a scintilla of evidence for that assertion, as Andersen and Garry made clear by cogently explaining at the July hearing called by conspiracy-addled House Republicans how the normal process of scientific research led them to the paper’s conclusions.
Last March, FBI Director Christopher Wray stated in an interview with Fox News that the bureau had concluded with “moderate confidence” that the virus had escaped from the Chinese lab, but he cited no evidence and didn’t explain its grounds.
The FBI’s assessment had been part of a survey of all U.S. intelligence agencies that largely contradicted the FBI’s position. In June, it was further contradicted by a report from the Office of the Director of National Intelligence, which refuted claims that the Chinese lab had played a role in the pandemic.
That brings us back to Ebright and Nickels. Although insults and invective are hardly uncommon in exchanges over COVID’s origins, their contributions have often carried a remarkably noxious tone.
The defense by both that they never compared the complainants to Pol Pot or Mengele or characterized them as murderers may be true as far as it goes. But it’s too clever by half. The complainants didn’t say in their letter to Rutgers that they themselves were necessarily the targets of Ebright’s and Nickels’ odious comparisons. Their complaint says the pair had “made comparisons of working scientists” — i.e., other scientists — “to historical war criminals and mass murderers.”
So let’s look at the record.
Ebright has repeatedly intimated that Fauci is a murderer, based on his view that his agency funded dangerous virology research in the Chinese lab that produced the pandemic. There is no evidence that any research the U.S. government funded in China produced the SARS-CoV-2 virus, or even that any such research at that lab was scientifically possible.
On Nov. 13, Ebright wrote of Fauci, “any person whose violations of U.S. government policies … resulted in 20 million deaths is, by any rational standard, a murderer.” It’s unclear what “violations” he was referring to.
In a June 27 tweet, Ebright described Fauci as “an octogenarian serially misfeasant, serially malfeasant, serially perjurious, former bureaucrat likely to face criminal charges after Jan 2025” (i.e., presumably assuming that Donald Trump would then take office again).
On Dec. 23 he tweeted that the “only option” to “mitigate the negative effects” of the proximal origin paper was the referral of Andersen and his colleagues “for criminal prosecution.”
On July 10, 2021, Ebright responded with the following comment to a tweet that apparently had alluded to critics of the lab-leak theory: “Sociopaths will be sociopaths … See Mengele. See Ishii.” The latter reference is to Shirō Ishii, who headed Japan’s World War II bioweapons program, which has been blamed for the deaths of as many as 300,000 people.
On Sept. 5 and 6, 2022, Ebright summarized the case for the lab-leak hypothesis, which he tied to “labs conducting world’s largest research program on bat SARS-like coronaviruses.” He ended the thread with the phrase “The banality of evil” — philosopher Hannah Arendt’s description of the impression left on her by Adolph Eichmann, the architect of the Nazi program of Jewish genocide, whose trial in Israel she reported on.
Nickels, in addition to posting the Mengele-linked film clip, earlier this month tweeted “massive respect to … military veterans that have taken a stand” against scientists he asserted had lied about research “impacting national security.” He called the behavior of such scientists “treasonous” and he specifically named among those deserving respect, one Andrew G. Huff.
One day earlier, Huff, who labels the zoonosis theory a “lie,” tweeted a call for Fauci, Daszak and virologist Ralph Baric of the University of North Carolina to be hauled before a military tribunal. Subsequently, he tweeted that his followers had voted in an online poll that if convicted, they should be hanged. He illustrated that tweet with a film clip of three people plunging to their deaths on a gallows.
The ball is now in Rutgers’ court. The university says the complaint “will be forwarded to the appropriate offices for review.” It didn’t say what issues would be considered. But certainly a determination would be warranted of whether its faculty members’ actions conform to the school’s policy on free expression, which frowns on actions or behaviors that “threaten individuals or cause an injury to someone” or “harass, threaten violence, or intimidate others.”
Whatever the outcome is of any such inquiry, the scientific community is right to be appalled by Ebright’s and Nickels’ activities. There’s vast latitude in science for disagreement and debate, but calling one’s adversaries or critics criminals or traitors, or placing them in the same category as Mengele, Eichmann and Pol Pot? That isn’t scientific debate.
In the world of science, the reputations of Andersen, Worobey, Garry, Holmes and Rambaut are secure; their finding that COVID most likely originated in the wildlife trade has not only held up over time but also been validated by subsequent studies. The same is true of the other eight signatories of the complaint letter, and Fauci and Daszak (who are not signatories).
Ebright and Nickels? They may be a different story.

5 Great Stargazing Trains
Stargazing, it turns out, doesn’t have to be a stationary activity.
On railway lines around the world, from the Arctic Circle to New Zealand, a select set of evening train excursions take riders deep into dark-sky territory — some en route to remote station stops decked out with telescopes, others featuring onboard astronomers.
These five rail journeys (all of which are accessible) range from two- to three-hour desert outings to a hunt for the northern lights. One route even has a planetarium on rails. All promise a renewed appreciation of train travel — and of our pale blue dot’s improbable place in the cosmos.
Nevada
The Great Basin Star Train
Any stargazing train worth its salt requires one thing: a dark sky. The Star Train resoundingly checks that box, traveling through a part of eastern Nevada that is one of the least-populated places in the lower 48.
Run by the Nevada Northern Railway in partnership with nearby Great Basin National Park, the train departs the historic East Ely Depot, in Ely, Nev., early enough in the evening to catch the sunset over the Steptoe Valley, and then cruises through darkening skies to its destination: a remote corner of the desert appropriately called Star Flat, where a stargazing platform outfitted with telescopes awaits. There, riders disembark (equipped with red-light necklaces to help preserve their night vision) and take turns viewing the cosmos, guided by professional astronomers. (Last year’s onboard stargazing guides came from Caltech; in previous seasons, the National Park Service’s Dark Rangers, who specialize in night-sky activities, accompanied trips.)
The Star Train makes its two-and-a-half-hour round-trip journey most Friday evenings between mid-May and mid-September, and tickets ($65 for adults) can sell out almost a year in advance — though members of the Nevada Northern Railway Museum get early access. Alternatively, the railroad’s more frequent Sunset, Stars and Champagne excursions trade telescopes for desert sundowners but feature the same expert stargazers and the same Nevada night sky, which is often dark enough to see the Milky Way with the naked eye.
New Mexico
The Stargazer
While plenty of heritage railroads across the United States offer twilight rides and nighttime excursions, at the moment there’s only one other dedicated, regularly scheduled stargazing train in North America besides the Star Train: the Stargazer, operated by Sky Railway, in Santa Fe, N.M.
Much like its Nevada counterpart, the Stargazer makes a two-and-a-half-hour round trip through dark-sky country, though in this case, the journey really is the destination, because it doesn’t make any stops. More of a rolling night-sky revue, the Stargazer features live music and professional astronomers who share their celestial knowledge and stories as the train rumbles into the vast Galisteo Basin south of Santa Fe. Sky Railway’s colorfully painted trains feature heated, enclosed passenger cars to stave off the evening chill and flatbed cars open to the night sky.
Departing from the Santa Fe Depot downtown, the train normally runs once a month (adult tickets from $139, including a champagne welcome toast). Sky Railway also occasionally schedules excursions for special celestial events.
New Zealand
Matariki Rail Experience
With its alpine landscapes and rugged coastline, New Zealand’s South Island is practically tailor-made for scenic daytime train journeys. But when night falls, the sparsely populated island — home to the Southern Hemisphere’s largest International Dark Sky Reserve — is heaven for stargazers, too.
This year, Great Journeys New Zealand, which operates the country’s tourist-centric long-distance trains, is offering a special nighttime run of the Coastal Pacific, whose route skirts the South Island’s northeastern coast. Timed to Matariki, the Maori new year, which is heralded by the first rising of the Pleiades star cluster, the eight-hour round trip from Christchurch is a cultural and astronomical celebration.
After the first half of a four-course onboard dinner, the train arrives in Kaikoura, in dark-sky country, for a guided stargazing stop with a range of telescopes — and fire pits and a night market. (The rain plan involves a virtual stargazing session at the local museum using virtual reality headsets.) Dinner resumes back on the train as it returns to Christchurch. This is a strictly limited engagement, on the rails for one night only: July 11, for 499 New Zealand dollars, about $295, per person.
In the far northern reaches of Norway, inside the Arctic Circle, you can ride a train that chases another wonder of the night sky: the aurora borealis. Twice a week from October to March, the Northern Lights Train takes its riders into the dark polar night in pursuit of the aurora’s celestial light show.
From the remote town of Narvik, the train travels along the Ofoten Railway, the northernmost passenger rail line in Western Europe. The destination on this three-hour round-trip excursion (1,495 kroner, or about $160) is Katterat, a mountain village accessible only by rail and free of light pollution, making it an ideal place to spot the aurora. At the Katterat station, local guides and a campfire cookout await, as does a lavvu, the traditional tent used by the Sami people of northern Scandinavia, offering a respite from the cold (as well as hot drinks and an open fire for roasting sausages).
And aboard the train, the lights stay off, which means that on a clear night, you might even catch the northern lights on the way there and back.
Leave it to Japan to take the stargazing train to another level.
The High Rail 1375 train — so named because it runs along Japan’s highest-elevation railway line (the high point is 1,375 meters, or roughly 4,500 feet, above sea level) — is one of JR East’s deliberately unhurried Joyful Trains, which the railway company describes as “not only a means of transportation, but also a package of various pleasures.” This astronomy-themed train certainly packs plenty of joy into its two cars, with seat upholstery inspired by constellations, a snack bar, a souvenir shop and a planetarium car with a library of astronomy books and images of the night sky projected onto its domed ceiling.
The train makes two daytime runs along the mountainous Koumi Line, taking a little over two hours to travel between Kobuchizawa (accessible by express train from Tokyo) and Komoro. But the main event is the High Rail Hoshizora (“Starry Sky”) evening trip, which includes an extended stop at Nobeyama Station (the highest in the country) for a guided stargazing session. A one-way ride on High Rail 1375, which runs on weekends and occasional weekdays, requires a seat reservation if you’re traveling on a Japan Rail pass, or a stand-alone ticket plus seat reservation (2,440 yen, or about $15). And remember to preorder a special “Starry Sky” bento box.

A Physicist Who Thinks in Poetry from the Cosmic Edge
Much of the praise for Chanda Prescod-Weinstein’s debut book in 2021, “The Disordered Cosmos: A Journey Into Dark Matter, Spacetime, and Dreams Deferred,” lauded the way she used personal experiences in physics to discuss the social and political inequities that exist alongside scientific breakthroughs.
“It contains the narrative of dreams deferred,” Dr. Prescod-Weinstein, a physicist at the University of New Hampshire, explained in April at a bookstore in Chicago. But its very existence, she said, also “represented a dream deferred, because that was not the dream of what my first book was going to be.”
Her second book reclaims that dream. Released on April 7, “The Edge of Space-Time: Particles, Poetry, and the Cosmic Dream Boogie” is less pain and more play, a homage to the big questions that made Dr. Prescod-Weinstein want to become a physicist in the first place. She begins the book by asserting that it is humanity’s duty to uncover and share the story of our universe. Her latest offering toward that duty is a journey through physics that is tightly bound to her own cultural roots.
In the midst of a multicity book tour, Dr. Prescod-Weinstein spoke with The New York Times about guiding readers through the cosmos from her own point of view and about some of the art, poetry and literature she drew on to shape that journey. This conversation has been edited for brevity and clarity.
Why include so many references to poetry in a book about physics?
I knew poetry before I knew physics. It was part of my upbringing. I loved A.A. Milne’s “Now We Are Six” and Edward Lear’s “Nonsense Limericks.” Both of my books draw their subtitles from Langston Hughes’s “Montage of a Dream Deferred.”
Adrienne Rich’s poem “The Burning of Paper Instead of Children” became a guiding light for how my work would move in the world. It also opened up for me that I need language. That’s true among physicists. Even an equation is a sentence; even an equation is telling a story.
As physicists, we’re always working in language to connect what we learn with what we know. Poetry is one of the first places that my brain goes to draw those links. Language, as it moves in my brain, is often in Hughes and Rich and Shakespeare. Those are the lines that flicker up for me.
What if we got away from the argument that doing cosmology and particle physics is practical or materially valuable? Then we have to accept that we’re like the poets. What we do is important culturally in the same way poetry is. A piece of this book is me saying there is value in banding with the poets, and fighting for the value of being curious and trying to articulate the world with whatever tools are available to us. Not for the purposes of selling something, but for the purpose of fulfilling our humanity.
Another theme throughout the book is the story of Lewis Carroll’s Alice and her adventures in Wonderland.
Being a science adviser on future installments in The Legendborn Cycle, a fantasy series written by Tracy Deonn, is one reason Alice is in my book. It has allowed me to be open to the playful side that physics, as a Black queer person, can take from you. I wanted the book to be whimsical, because that’s who I was when I first arrived in physics, and that’s who I want to be when I die.
Part of the call of quantum physics is to change what our sense and sensibility are. When you look at the world through this framework — like the idea that particles have spin but don’t really spin — it sounds like nonsense. Except that’s literally how the universe works. Physics is our “through the looking glass.” It’s real.
Your first chapter invites readers to reflect on the metaphors used to describe the universe, like the “fabric” of space-time or electromagnetic “fields.” Why open in this way?
A lot of books about quantum physics start with its history. I wanted as much as possible not to just do that. I had actually planned to start it with the Stern-Gerlach experiment of 1922. But then I read an essay by the poet Natasha Trethewey about abiding metaphors and started to ask myself what the abiding metaphors of my physics training were.
We don’t ever take time in our classes to ask, “What do we mean when we say ‘space’? What do we mean when we say ‘space-time’?” There are these metaphysical questions that I often told myself were for the philosophers. This book was me letting myself think of them as physics.
One metaphor you invoke is the “edge” — not only the edge of the universe and of scientists’ understanding, but also existing at the edge of certain identities.
In “Disordered Cosmos,” I talked a lot about being at the margin and looking toward the center. With “The Edge of Space-Time,” I’m choosing to make the margin the center of the story. Part of that was me fully embracing what makes me the physicist I am. I’m an L.A. Dodgers fan. I love “Alice in Wonderland.” I love “Star Trek.” There’s lots of all of that in the book.
Picking a metaphor is a culturally situated decision. I wrote a line that says black holes are the best laid edges in the universe. I did, at some point, think that only some people were going to get this. But for people who don’t understand the reference to Black hairstyles, the sentence is still legible. And for those who do, it will feel like we just had an in-group moment. Anyone who thinks about laying their edges deserves to have an in-group moment in a physics book. Because we are physics, too.
Black students are often told that if you want to be a physicist, then you will make yourself as close to such-and-such mold as possible. At a young age, we have this understanding that whiteness and science are associated with each other, but we are also witnessing in ourselves that this can’t be entirely correct. There’s this narration of, “Well, sure, you can be Black in physics, but that means you have to acclimate to the ‘in physics’ part, and never that physics has to acclimate to the Black part.”
I use the example of rapper Big K.R.I.T.’s song “My Sub Pt. 3 (Big Bang),” in which someone tries to wire up subwoofers in his car but fries the wires because he doesn’t ground them properly. I don’t know if Big K.R.I.T. would think of this as a science story, but I think we should learn to read it as one. Not to contain it in science, but to say it overlaps there. This can be a rap song. It can be about the cultural significance of subwoofers and the Big Bang as a metaphor for the beat. And it can also be about cosmology and about how everybody who wires up cars or does this kind of work is a scientist, too.
How do you want readers to approach this book?
There is this feeling that you’re supposed to read a book like this and walk away an expert. That’s actually not the point of this book at all. The point is to wander through physics. Even if math terrifies you, you are entitled to spend some time with it.
And so here, I have made you a book with a bunch of tidbits on the oddities of the universe. The universe is stranger and more queer and more wonderful and more full of possibility than whatever limitations you might be experiencing right now. Physics challenges what we are told are social norms. For example, non-trinary neutrinos are fundamental to our standard model of physics.
“Non-trinary,” as in they shift between three different forms.
Non-trinary is natural. It’s such a challenge to the current anti-trans rhetoric that says people can only ever be one thing.
I don’t need my book to be the most important thing that someone reads. But I want it to be a source of hope. If it reminds you that, as my mom says, the universe is bigger than the bad things that are happening to us, then that’s all you need to remember. I’m good with that.

Footage shows Central Valley dairy workers kicking young calves, pulling them with pliers
In late February, animal rights activists flew a drone over a calf ranch in the Central Valley and watched as workers kicked and punched the animals.
For the record:
7:15 p.m. May 12, 2026This article has been updated to reflect that no calves from Agresti Calf Ranch have ever gone on to be used for Clover Sonoma milk supplies, and the calf ranch opened only in 2025. In additional comments, Clover Sonoma also said in the future, no animals from Agresti Calf Ranch will be part of its supply.
Footage reviewed by The Times shows a worker pulling a calf by the nose with pliers.
It shows two workers removing the budding horns of a calf with a hot iron. While one held the frightened animal’s head, the other — wearing a sweatshirt with an image of the Virgin Mary — applied the iron to a horn. After a puff of smoke, the calf fell to its side, appearing motionless.

Both male and female calves produce horns. To prevent injury to the animals and their handlers, these are commonly removed. Humane guidelines require anesthesia.
The footage was collected by the group Direct Action Everywhere, known for tactics including releasing beagles from medical breeding facilities and abused calves from farms. It was shot at the Agresti Calf Ranch in Ceres, near Modesto, which is certified by the American Humane Society for its ethical treatment of animals. The workers could not be reached for comment. One was subsequently terminated, the Humane Society said.
The Agresti Calf Ranch opened in 2025 and is operated by the owners of Double D Dairy, just up the road. Double D Dairy owns more than 10,000 cows across several operations.
The owner of Double D, Dominic Assali, declined to answer questions in person. A phone number for the dairy online is disconnected. In response to an email to his personal account, Assali said, “Animal welfare and safety are incredibly important to us, and we have a zero-tolerance policy for any mistreatment.
“We’ll always take immediate, thorough action to address any operational issues, as we have in this instance,” the email said.
The American Humane Society is a 150-year-old nonprofit focused on animal welfare. Among other things, it certifies animal safety on farms as well as on movie sets. In a statement, it said only 10% of animals raised on farms in the U.S. are certified as humanely treated.
Assali is the grandson of the farm’s founders, Harold and Marlene Agresti. He is a board member of Western United Dairies, the largest dairy trade group in California.
The mistreatment captured on video has also created a headache for a prominent California sustainable milk brand, Clover Sonoma, based in Sonoma County.
It gets 10% to 15% of its milk from Double D, and Assali and his family are featured on Clover Sonoma’s website. No calves from Agresti Calf Ranch have ever gone on to be used in Clover Sonoma milk supplies, the company said in a statement. It’s unclear whether the abused calves were being raised for beef or dairy.
A Clover Sonoma sign hung outside the main dairy complex on a recent visit.
Clover Sonoma markets its milk, yogurt and cheese products as humanely sourced and environmentally sound. It was the first dairy company to receive a cruelty-free certification from the American Humane Society in 2000. The website also features a “Our Promise” page, which states the company demands “the humane treatment of animals.”
“We were deeply concerned by the reported mistreatment of some cows captured on video at Agresti Calf Ranch during a separate cow operation,” the company said in an email.
“The rough handling shown at Agresti Calf Ranch is contrary and inconsistent with the humane practices we have fostered for decades and which we demand of all our suppliers.”
Clover Sonoma said it suspended business with Double D as soon as it became aware of the incidents and began “a rigorous audit,” which just ended.
“Clover and the American Humane Society have concluded that the mistreatment was an isolated issue, not systemic or reflective of Agresti Calf Ranch’s personnel. Corrections have been made, including the termination of the employee in the video. As such, we are comfortable reinstating the milk from Double D Dairy.”
After this story published, Clover went further and said a condition of Double D’s reinstatement will be that no animals from Agresti Calf Ranch will be part of Clover’s dairy supply.
A statement from the Humane Society said Clover Sonoma is working with Double D to strengthen its whistleblower policy and training, and has “reiterated its commitment to ongoing independent, third-party audits,” with both announced and unannounced visits.
Clover Sonoma mainly buys and processes milk from dairies in verdant Sonoma County, as the company’s marketing suggests. Double D Dairy is one of its few suppliers in the Central Valley, which is associated more with industrial-scale agriculture.
On a recent weekday, the calf ranch and dairy farm were visible from a public road. Holstein calves, a popular dairy breed, could be seen in cages through small trees in front of the enclosures. The sound of mooing and a pressure washer could be heard. The smell of manure and dirt wafted in the humid air.
Most dairy companies remove calves from their mothers after birth, raising them separately so they don’t take the mother’s commercially valuable milk. Some dairy farms send calves out to third-party calf ranches for rearing. Others raise them on-site. Female calves are typically raised to become milk cows. Male calves are sent away to become beef or other meat-based products, such as pet food.
A 2025 State Water Board document shows the farm houses an average of 700 calves at any one time, with a maximum 1,400.
The Direct Action Everywhere activists were recently on a public road near Double D’s main farm, flying a drone over the property. Within 30 minutes of their arrival, seven Stanislaus County sheriff’s vehicles arrived and surrounded the activists.
A heavily armed officer asked to see the drone pilot’s Federal Aviation Administration license, which he provided. After confirming it was valid, a sheriff’s deputy — one of nine at the scene — told the activists they could remain on the road but could not trespass.
Asked about the heavy response, a deputy said there had been several recent violent incidents from animal rights groups at the site, and mentioned the groups had sent in “busloads” of activists.
The Times reached out to the Sheriff’s Office to get more details about those events but did not get a response.
Temple Grandin, author and professor of livestock medicine at Colorado State University, said that punching and kicking livestock is considered abusive.
An expert in livestock welfare, she said that handlers can tap, push and nudge animals. But if the level of force goes beyond what could bend the side of a cardboard box, “it’s abuse. Period.”
She said the calves’ reaction to the hot iron indicates that pain medication, such as lidocaine, was not applied before the procedure. Double D did not respond to a question about whether medication was given before the procedure.
