RFK Jr. speaks candidly about his gravelly voice: ‘If I could sound better, I would’
There was a time before the turn of the millennium when Robert F. Kennedy Jr. gave a full-throated accounting of himself and the things he cared about. He recalls his voice then as “unusually strong,” so much so that he could fill large auditoriums with his words. No amplification needed.
The independent presidential candidate recounts those times somewhat wistfully, telling interviewers that he “can’t stand” the sound of his voice today — sometimes choked, halting and slightly tremulous.
The cause of RFK Jr.’s vocal distress? Spasmodic dysphonia, a rare neurological condition, in which an abnormality in the brain’s neural network results in involuntary spasms of the muscles that open or close the vocal cords.
My voice doesn’t really get tired. It just sounds terrible.
— Robert F. Kennedy Jr.
“I feel sorry for the people who have to listen to me,” Kennedy said in a phone interview with The Times, his voice as strained as it sounds in his public appearances. “My voice doesn’t really get tired. It just sounds terrible. But the injury is neurological, so actually the more I use the voice the stronger it tends to get.”
Since declaring his bid for the presidency a year ago, the 70-year-old environmental lawyer has discussed his frayed voice only on occasion, usually when asked by a reporter. He told The Times: “If I could sound better, I would.”
SD, as it’s known, affects about 50,000 people in North America, although that estimate may be off because of undiagnosed and misdiagnosed cases, according to Dysphonia International, a nonprofit that organizes support groups and funds research.
As with Kennedy, cases typically arise in midlife, though increased recognition of SD has led to more people being diagnosed at younger ages. The disorder, also known as laryngeal dystonia, hits women more often than men.
Internet searches for the condition have spiked, as Kennedy and his gravelly voice have become staples on the news. When Dysphonia International posted an article answering the query, “What is wrong with RFK Jr.’s voice?,” it got at least 10 times the traffic of other items.
Those with SD usually have healthy vocal cords. Because of this, and the fact that it makes some people sound like they are on the verge of tears, some doctors once believed that the croaking or breathy vocalizations were tied to psychological trauma. They often prescribed treatment by a psychotherapist.
But in the early 1980s, researchers, including Dr. Herbert Dedo of UC San Francisco, recognized that SD was a condition rooted in the brain.
Researchers have not been able to find the cause or causes of the disorder. There is speculation that a genetic predisposition might be set off by some event — physical or emotional — that triggers a change in neural networks.
Some who live with SD say the spasms came out of the blue, seemingly unconnected to other events, while others report that it followed an emotionally devastating personal setback, an injury accident or a severe infection.
Kennedy said he was teaching at Pace University School of Law in White Plains, N.Y., in 1996 when he noticed a problem with his voice. He was 42.
His campaigns for clean water and other causes in those days meant that he traveled the country, sometimes appearing in court or giving speeches. He lectured, of course, in his law school classes and co-hosted a radio show. Asked whether it was hard to hear his voice gradually devolve, Kennedy said: “I would say it was ironic, because I made my living on my voice.”
“For years people asked me if I had any trauma at that time,” he said. “My life was a series of traumas … so there was nothing in particular that stood out.”
Kennedy was just approaching his 10th birthday when his uncle, President John F. Kennedy, was assassinated. At 14, his father was fatally shot in Los Angeles, on the night he won California’s 1968 Democratic primary for president.
RFK Jr. also lost two younger brothers: David died at age 28 of a heroin overdose in 1984 and Michael died in 1997 in a skiing accident in Aspen, Colo., while on the slopes with family members, including then-43-year-old RFK Jr.
It was much more recently, and two decades after the speech disorder cropped up, that Kennedy came up with a theory about a possible cause. Like many of his highly controversial and oft-debunked pronouncements in recent years, it involved a familiar culprit — a vaccine.
Kennedy said that while he was preparing litigation against the makers of flu vaccines in 2016, his research led him to the written inserts that manufacturers package along with the medications. He said he saw spasmodic dysphonia on a long list of possible side effects. “That was the first I ever realized that,” he said.
Although he acknowledged there is no proof of a connection between the flu vaccines he once received annually and SD, he told The Times he continues to view the flu vaccine as “at least a potential culprit.”
Kennedy said he no longer has the flu vaccine paperwork that triggered his suspicion, but his campaign forwarded a written disclosure for a later flu vaccine. The 24-page document lists commonly recognized adverse reactions, including pain, swelling, muscle aches and fever.
It also lists dozens of less common reactions that users said they experienced. “Dysphonia” is on the list, though the paperwork adds that “it is not always possible to reliably estimate their frequency or establish a causal relationship to the vaccine.”
Public health experts have slammed Kennedy and his anti-vaccine group, Children’s Health Defense, for advancing unsubstantiated claims, including that vaccines cause autism and that COVID-19 vaccines caused a spike of sudden deaths among healthy young people.
Dr. Timothy Brewer, a professor of medicine and epidemiology at UCLA, said an additional study cited by the Kennedy campaign to The Times referred to reported adverse reactions that were unverified and extremely rare.
“We shouldn’t minimize risks or overstate them,” Brewer said. “With these influenza vaccines there are real benefits that so far outweigh the potential harm cited here that it’s not worth considering those types of reactions further.”
Anyone with concerns about influenza vaccine side effects should consult their physician, he said.
So what does research suggest about SD?
“We just don’t know what brings it on,” said Dr. Michael Johns, director of the USC Voice Center and an authority on spasmodic dysphonia. “Intubation, emotional trauma, physical trauma, infections and vaccinations are all things that are incredibly common. And it’s very hard to pin causation on something that is so common when this is a condition that is so rare.”
No two SD sufferers sound the same. For some, spasms push the vocal cords too far apart, causing breathy and nearly inaudible speech. For others, such as Kennedy, the larynx muscles push the vocal cords closer together, creating a strained or strangled delivery.
“I would say it was a very, very slow progression,” Kennedy said last week. “I think my voice was getting worse and worse.”
There were times when mornings were especially difficult.
“When I opened my mouth, I would have no idea what would come out, if anything,” he said.
One of the most common treatments for the disorder is injecting Botox into the muscles that bring the vocal cords together.
Kennedy said he received Botox injections every three or four months for about 10 years. But he called the treatment “not a good fit for me,” because he was “super sensitive to the Botox.” He recalled losing his voice entirely after the injections, before it would return days later, somewhat smoother.
Looking for a surgical solution, Kennedy traveled to Japan in May, 2022. Surgeons in Kyoto implanted a titanium bridge between his vocal cords (also known as vocal folds) to keep them from pressing together.
He told a YouTube interviewer last year that his voice was getting “better and better,” an improvement he credited to the surgery and to alternative therapies, including chiropractic care.
The procedure has not been approved by regulators in the U.S.
Johns cautioned that titanium bridge surgeries haven’t been consistently effective or durable and said there have been reports of the devices fracturing, despite being implanted by reputable doctors. He suggested that the more promising avenue for breakthroughs will be in treating the “primary condition, which is in the brain.”
Researchers are now trying to find the locations in the brain that send faulty signals to the larynx. Once those neural centers are located, doctors might use deep stimulation — like a pacemaker for the brain — to block the abnormal signals that cause vocal spasms. (Deep brain stimulation is used to treat patients with Parkinson’s disease and other afflictions.)
Long and grueling presidential campaigns have stolen the voice of many candidates. But Kennedy said he is not concerned, since his condition is based on a neural disturbance, not one in his voice box.
“Actually, the more I use the voice, the stronger it tends to get,” he said. “It warms up when I speak.”
Kennedy was asked whether the loss of his full voice felt particularly frustrating, given his family’s legacy of ringing oratory. He replied, his voice still raspy, “Like I said, it’s ironic.”

Diablo Canyon clears last California permit hurdle to keep running
Central Coast Water authorities approved waste discharge permits for Diablo Canyon nuclear plant Thursday, making it nearly certain it will remain running through 2030, and potentially through 2045.
The Pacific Gas & Electric-owned plant was originally supposed to shut down in 2025, but lawmakers extended that deadline by five years in 2022, fearing power shortages if a plant that provides about 9 percent the state’s electricity were to shut off.
In December, Diablo Canyon received a key permit from the California Coastal Commission through an agreement that involved PG&E giving up about 12,000 acres of nearby land for conservation in exchange for the loss of marine life caused by the plant’s operations.
Today’s 6-0 vote by the Central Coast Regional Water Board approved PG&E’s plans to limit discharges of pollutants into the water and continue to run its “once-through cooling system.” The cooling technology flushes ocean water through the plant to absorb heat and discharges it, killing what the Coastal Commission estimated to be two billion fish each year.
The board also granted the plant a certification under the Clean Water Act, the last state regulatory hurdle the facility needed to clear before the federal Nuclear Regulatory Commission (NRC) is allowed to renew its permit through 2045.
The new regional water board permit made several changes since the last one was issued in 1990. One was a first-time limit on the chemical tributyltin-10, a toxic, internationally-banned compound added to paint to prevent organisms from growing on ship hulls.
Additional changes stemmed from a 2025 Supreme Court ruling that said if pollutant permits like this one impose specific water quality requirements, they must also specify how to meet them.
The plant’s biggest water quality impact is the heated water it discharges into the ocean, and that part of the permit remains unchanged. Radioactive waste from the plant is regulated not by the state but by the NRC.
California state law only allows the plant to remain open to 2030, but some lawmakers and regulators have already expressed interest in another extension given growing electricity demand and the plant’s role in providing carbon-free power to the grid.
Some board members raised concerns about granting a certification that would allow the NRC to reauthorize the plant’s permits through 2045.
“There’s every reason to think the California entities responsible for making the decision about continuing operation, namely the California [Independent System Operator] and the Energy Commission, all of them are sort of leaning toward continuing to operate this facility,” said boardmember Dominic Roques. “I’d like us to be consistent with state law at least, and imply that we are consistent with ending operation at five years.”
Other board members noted that regulators could revisit the permits in five years or sooner if state and federal laws changes, and the board ultimately approved the permit.

Deadly bird flu found in California elephant seals for the first time
The H5N1 bird flu virus that devastated South American elephant seal populations has been confirmed in seals at California’s Año Nuevo State Park, researchers from UC Davis and UC Santa Cruz announced Wednesday.
The virus has ravaged wild, commercial and domestic animals across the globe and was found last week in seven weaned pups. The confirmation came from the U.S. Department of Agriculture’s National Veterinary Services Laboratory in Ames, Iowa.
“This is exceptionally rapid detection of an outbreak in free-ranging marine mammals,” said Professor Christine Johnson, director of the Institute for Pandemic Insights at UC Davis’ Weill School of Veterinary Medicine. “We have most likely identified the very first cases here because of coordinated teams that have been on high alert with active surveillance for this disease for some time.”
Since last week, when researchers began noticing neurological and respoiratory signs of the disease in some animals, 30 seals have died, said Roxanne Beltran, a professor of ecology and evolutionary biology at UC Santa Cruz. Twenty-nine were weaned pups and the other was an adult male. The team has so far confirmed the virus in only seven of the dead pups.
Infected animals often have tremors convulsions, seizures and muscle weakness, Johnson said.
Beltran said teams from UC Santa Cruz, UC Davis and California State Parks monitor the animals 260 days of the year, “including every day from December 15 to March 1” when the animals typically come ashore to breed, give birth and nurse.
The concerning behavior and deaths were first noticed Feb. 19.
“This is one of the most well-studied elephant seal colonies on the planet,” she said. “We know the seals so well that it’s very obvious to us when something is abnormal. And so my team was out that morning and we observed abnormal behaviors in seals and increased mortality that we had not seen the day before in those exact same locations. So we were very confident that we caught the beginning of this outbreak.”
In late 2022, the virus decimated southern elephant seal populations in South America and several sub-Antarctic Islands. At some colonies in Argentina, 97% of pups died, while on South Georgia Island, researchers reported a 47% decline in breeding females between 2022 and 2024. Researchers believe tens of thousands of animals died.
More than 30,000 sea lions in Peru and Chile died between 2022 and 2024. In Argentina, roughly 1,300 sea lions and fur seals perished.
At the time, researchers were not sure why northern Pacific populations were not infected, but suspected previous or milder strains of the virus conferred some immunity.
The virus is better known in the U.S. for sweeping through the nation’s dairy herds, where it infected dozens of dairy workers, millions of cows and thousands of wild, feral and domestic mammals. It’s also been found in wild birds and killed millions of commercial chickens, geese and ducks.
Two Americans have died from the virus since 2024, and 71 have been infected. The vast majority were dairy or commercial poultry workers. One death was that of a Louisiana man who had underlying conditions and was believed to have been exposed via backyard poultry or wild birds.
Scientists at UC Santa Cruz and UC Davis increased their surveillance of the elephant seals in Año Nuevo in recent years. The catastrophic effect of the disease prompted worry that it would spread to California elephant seals, said Beltran, whose lab leads UC Santa Cruz’s northern elephant seal research program at Año Nuevo.
Johnson, the UC Davis researcher, said the team has been working with stranding networks across the Pacific region for several years — sampling the tissue of birds, elephant seals and other marine mammals. They have not seen the virus in other California marine mammals. Two previous outbreaks of bird flu in U.S. marine mammals occurred in Maine in 2022 and Washington in 2023, affecting gray and harbor seals.
The virus in the animals has not yet been fully sequenced, so it’s unclear how the animals were exposed.
“We think the transmission is actually from dead and dying sea birds” living among the sea lions, Johnson said. “But we’ll certainly be investigating if there’s any mammal-to-mammal transmission.”
Genetic sequencing from southern elephant seal populations in Argentina suggested that version of the virus had acquired mutations that allowed it to pass between mammals.
The H5N1 virus was first detected in geese in China in 1996. Since then it has spread across the globe, reaching North America in 2021. The only continent where it has not been detected is Oceania.
Año Nuevo State Park, just north of Santa Cruz, is home to a colony of some 5,000 elephant seals during the winter breeding season. About 1,350 seals were on the beach when the outbreak began. Other large California colonies are located at Piedras Blancas and Point Reyes National Sea Shore. Most of those animals — roughly 900 — are weaned pups.
It’s “important to keep this in context. So far, avian influenza has affected only a small proportion of the weaned at this time, and there are still thousands of apparently healthy animals in the population,” Beltran said in a press conference.
Public access to the park has been closed and guided elephant seal tours canceled.
Health and wildlife officials urge beachgoers to keep a safe distance from wildlife and keep dogs leashed because the virus is contagious.

When slowing down can save a life: Training L.A. law enforcement to understand autism
Kate Movius moved among a roomful of Los Angeles County sheriff’s deputies, passing out a pop trivia quiz and paper prism glasses.
She told them to put on the vision-distorting glasses, and to write with their nondominant hand. As they filled out the tests, Movius moved about the City of Industry classroom pounding abruptly on tables. Then came the cowbell. An aide flashed the overhead lights on and off at random. The goal was to help the deputies understand the feeling of sensory overwhelm, which many autistic people experience when incoming stimulation exceeds their capacity to process.
“So what can you do to assist somebody, or de-escalate somebody, or get information from someone who suffers from a sensory disorder?” Movius asked the rattled crowd afterward. “We can minimize sensory input. … That might be the difference between them being able to stay calm and them taking off.”
Movius, founder of the consultancy Autism Interaction Solutions, is one of a growing number of people around the U.S. working to teach law enforcement agencies to recognize autistic behaviors and ensure that encounters between neurodevelopmentally disabled people and law enforcement end safely.
She and City of Industry Mayor Cory Moss later passed out bags filled with tools donated by the city to aid interactions: a pair of noise-damping headphones to decrease auditory input, a whiteboard, a set of communication cards with words and images to point to, fidget toys to calm and distract.
“The thing about autistic behavior when it comes to law enforcement is a lot of it may look suspicious, and a lot of it may feel very disrespectful,” said Movius, who is also the parent of an autistic 25-year-old man. Responding officers, she said, “are not coming in thinking, ‘Could this be a developmentally disabled person?’ I would love for them to have that in the back of their minds.”

Autism spectrum disorder is a developmental condition that manifests differently in nearly every person who has it. Symptoms cluster around difficulties in communication, social interaction and sensory processing.
An autistic person stopped by police might hold the officer’s gaze intensely or not look at them at all. They may repeat a phrase from a movie, repeat the officer’s question or temporarily lose their ability to speak. They might flee.
All are common involuntary responses for an autistic person in a stressful situation, which a sudden encounter with law enforcement almost invariably is. To someone unfamiliar with the condition, all could be mistaken for intoxication, defiance or guilt.
Autism rates in the U.S. have increased nearly fivefold since the Centers for Disease Control began tracking diagnoses in 2000, a rise experts attribute to broadening diagnostic criteria and better efforts to identify children who have the condition.
The CDC now estimates that 1 in 31 U.S. 8-year-olds is autistic. In California, the rate is closer to 1 in 22 children.
As diverse as the autistic population is, people across the spectrum are more likely to be stopped by law enforcement than neurotypical peers.
About 15% of all people in the U.S. ages 18 to 24 have been stopped by police at some point in their lives, according to federal data. While the government doesn’t track encounters for disabled people specifically, a separate study found that 20% of autistic people ages 21 to 25 have been stopped, often after a report or officer observation of a person behaving unusually.
Some of these encounters have ended in tragedy.
In 2021, Los Angeles County sheriff’s deputies shot and permanently paralyzed a deaf autistic man after family members called 911 for help getting him to a hospital.
Isaias Cervantes, 25, had become distressed about a shopping trip and started pushing his mother, his family’s attorney said at the time. He resisted as two deputies attempted to handcuff him and one of the deputies shot him, according to a county report.
In 2024, Ryan Gainer’s family called 911 for support when the 15-year-old became agitated. Responding San Bernardino County sheriff‘s deputies shot and killed him outside his Apple Valley home.
Last year, police in Pocatello, Idaho, shot Victor Perez, 17, through a chain-link fence after the nonspeaking teenager did not heed their shouted commands. He died from his injuries in April.

As early as 2001, the FBI published a bulletin on police officers’ need to adjust their approach when interacting with autistic people.
“Officers should not interpret an autistic individual’s failure to respond to orders or questions as a lack of cooperation or as a reason for increased force,” the bulletin stated. “They also need to recognize that individuals with autism often confess to crimes that they did not commit or may respond to the last choice in a sequence presented in a question.”
But a review of multiple studies last year by Chapman University researchers found that while up to 60% of officers have been on a call involving an autistic person, only 5% to 40% had received any training on autism.
In response, universities, nonprofits and private consultants across the U.S. have developed curricula for law enforcement on how to recognize autistic behaviors and adapt accordingly.
The primary goal, Movius told deputies at November’s training session, is to slow interactions down to the greatest extent possible. Many autistic people require additional time to process auditory input and verbal responses, particularly in unfamiliar circumstances.
If at all possible, Movius said, wait 20 seconds for a response after asking a question. It may feel unnaturally long, she acknowledged. But every additional question or instruction fired in that time — what’s your name? Did you hear me? Look at me. What’s your name? — just decreases the likelihood that a person struggling to process will be able to respond at all.
Moss’ son, Brayden, then 17, was one of several teenagers and young adults with autism who spoke or wrote statements to be read to the deputies. The diversity of their speech patterns and physical mannerisms showed the breadth of the spectrum. Some were fluently verbal, while others communicated through signs and notes.
“This population is so diverse. It is so complicated. But if there’s anything that we can show [deputies] in here that will make them stop and think, ‘Hey, what if this is autism?’ … it is saving lives,” Moss said.

Some disability advocates cautioned that it takes more than isolated training sessions to ensure encounters end safely.
Judy Mark, co-founder and president of the nonprofit Disability Voices United, says she trained thousands of officers on safe autism interactions but stopped after Cervantes’ shooting. She now urges families concerned about an autistic child’s safety to call an ambulance rather than law enforcement.
“I have significant concern about these training sessions,” Mark said. “People get comfort from it, and the Sheriff’s Department can check the box.”
While not a panacea, supporters argue that a brief course is better than no preparation at all. Some years ago, Movius received a letter from a man whose profoundly autistic son slipped away as the family loaded their car at the beach. He opened the unlocked door of a police vehicle, climbed into the back and began to flail in distress.
Though surprised, the officer seated at the wheel de-escalated the situation and helped the young man find his family, the father wrote to Movius. He had just been to her training.
