Justine Doiron didn’t plan on becoming a recipe developer when she moved to New York in 2016. She was fresh out of Cornell University’s hospitality program and had embarked on a career in public relations. Cooking was just a hobby then.

Today, she’s better known by her online moniker Justine Snacks and shares recipe videos with 2.3 million followers on TikTok.

Ms. Doiron, 30, first gave TikTok a whirl in April 2020. Since the app’s main audience seemed to be teenagers, she geared her content toward them with trending recipes for sushi cakes and pasta flowers. Eventually, her style morphed into what she’s best known for today: approachable, veggie-forward recipes paired with stories from her day-to-day life.

She recently published “Justine Cooks: A Cookbook” and has another one in the works. All of Ms. Doiron’s recipe testing, on and off camera, is done in the kitchen of her 250-year-old wood frame house in the Crown Heights neighborhood in Brooklyn.

“I’m really building out my dream life in the house, because this year’s been the year of Martha Stewart and Ina Garten, and their resurgence of this ‘nostalgia core,’” she said.

Ms. Doiron lives with her fiancé, Eric Lipka, 31, an intelligence analyst, their French bulldog, Walter, and their rescue cat, Gladiator.

EARLY TO RISE I wake up at 6 a.m. if not earlier. I’ve been having a lot of trouble sleeping lately, which I guess just comes with age and general anxiety about things (love that). I also really like my mornings to myself. I use the first hour of the morning to ingest coffee like it’s my job and write down my general outline and plans for the week.

TO MARKET TO MARKET I go to the Carroll Gardens Greenmarket as my grossest self. I’m just pajamas-to-jeans, a T-shirt, a puffy jacket, a coat, beanie, puffy eyes and S.P.F. on my face, and I’m out the door by 7:30 a.m. I like seeing everything at its fullest potential. I don’t like to feel like I might have missed out something.

Carroll Gardens has ACQ Bread Co., which is my favorite bread in the entire city — it’s everyone’s favorite bread. They have a line down the block no matter how early I am to the market. Every two weeks I get their Living Bread, which has seeds and sprouts.

GUILTY PLEASURE Afterward, I pop into Trader Joe’s. It’s a 10-minute walk from the Carroll Gardens market, so the amount of guilt I feel walking into Trader Joe’s with two tote bags filled of vegetables that aren’t theirs, to get five cans of chickpeas, some edamame and some coffee creamer, is crazy, but it’s part of my routine. Then I take the subway home.

LEISURELY BREAKFAST My big luxury is a big, slow breakfast, my shower and being lazy for the next 90 minutes. For breakfast, I toast two slices of the Living Bread I just bought, and then I like to boil jammy eggs. I’m a three egg kind of girl, and I mash them up with chili, flaky salt, red wine vinegar, black pepper and I just put that on the toast. It’s a great time to get avocado, so if I have blessed myself with a ripened avocado and have that available, that’ll go on there too. Eric, if he’s lucky enough, and awake and hungry, will get the same.

FIXER UPPER Our house is amazing, but when we got it it needed some tender love and care. I really want a Brooklyn garden in the backyard (which is just concrete, let’s be honest). We’re making garden beds that have good drainage, and I’m watching the sun and seeing where it’ll go. Soon, I’ll start seeds on the third floor of the house.

TEST KITCHEN I’m usually so excited and inspired by ingredients, especially right when I get them, because nothing hits like the vegetables you just buy. They’re at their peak gorgeousness and freshness. I’m currently in the throes of working on book No. 2, so I do a quick little recipe test, or a quick little, “let’s put these flavors together with this ingredient and kind of see where it nets out.” Maybe this will turn into an idea further down the line. We’re not super hungry since we had a late breakfast, so it’s a little peckish recipe test snack.

EARLY BIRD I’m such a morning person and a lazy night person that sometimes we meet our friends for just drinks or aperitivo. Agi’s Counter is in our neighborhood, and that’s my favorite place. I like to get the window seat (if you know, you know) and just get something super cozy there for dinner.

CLEAN UP I have kept this habit since my 9-to-5 corporate days. I can’t start a week without feeling some semblance of: normalcy, control, clean. I just straighten the house, do whatever laundry I can and make sure the kitchen’s clean. It takes me about an hour, and I do it while listening to a podcast like “Las Culturistas.” It used to be so much more intense, but I’ve relaxed now that we have a dog and a cat and I share the home with somebody else. I realize I’ve let go of a lot of control of things, but the cleaning has stayed.

EARLY TO BED Eric and I are together most of the day, but we like to prioritize hanging out all in the same room. He might be logging on and finishing up some emails, while I read and prepare to fall asleep. I’ve really gotten into reading. I loved “The Wedding People” by Alison Espach and I’m getting back into reading Maggie O’Farrell — I leap at her books anytime they’re available on the library’s Libby app. I’m in this phase of my life where I completely understand how lucky I am to have so much peace and so much freedom with my schedule. I use that freedom to go to bed on the earlier side.

In a very short time, Mahmoud Khalil, the former Columbia University graduate student and pro-Palestinian activist who was questionably detained by federal immigration officials, has become a symbol of the Trump administration’s escalating antagonism toward elite universities. Columbia finds itself up against the impression that whatever it has done to combat what it perceived as antisemitism — suppressing campus protests of the war in Gaza with the help of the police; evicting and expelling rallying students; severing ties with a law professor who had been a vocal supporter of the Palestinian cause — it has not been nearly punitive enough.

However egregious these measures might seem to champions of civil liberty, they strike people like Jeffrey Lichtman as cowardly and insufficient. Last year, Mr. Lichtman, a lawyer, represented a Columbia student and former member of the Israel Defense Forces in a suit against the university after he was suspended for showering protesters with foul-smelling joke spray that sickened some of them. Columbia settled for close to $400,000. Still, Mr. Lichtman believes that the university is so rife with hatred and disrespect for Jewish interests that it “should be taken over by the federal government” — at least in the short term, he said to me recently.

Just before Mr. Khalil was apprehended, the Trump administration took the comparatively modest step of canceling $400 million of Columbia’s federal grants. A few days later, it warned 60 universities that a similar fate could await them. Among the schools listed were Harvard, Cornell and Johns Hopkins, where Michael Bloomberg, who once called President Trump “a carnival barking clown,” made a $1 billion gift in July.

The goal of the current White House to dismantle higher education — while running for the Senate, JD Vance plainly called universities the enemy — has elicited alarm from many quarters, but it is striking how little we have heard from the megadonor class. Their contributions of billions of dollars to major universities would suggest a significant investment in the mission (or at the very least a vain interest in keeping alive the buildings and centers and divisions to which they have purchased naming rights).

The quiet was punctured this week when Bill Ackman, the hedge-fund manager who was instrumental in getting Claudine Gay removed from the presidency at Harvard last year, weighed in on X. He did not express concern about potential cuts to universities; rather he wanted to say that only “financial and legal pressure” will get them back to a point at which “sanity” might prevail.

Under a different set of conditions, it would be easy to imagine wealthy Ivy League Democratic donors rising up to fill in the gaps left by an unwelcoming government. But in the current environment, the grievances of those donors — against diversity initiatives and unruly agitators — stand in precise alignment with the agenda in Washington.

Even before the cuts were announced, the Stand Columbia Society, a consortium of alumni and current and former faculty committed to dissecting the wonkier aspects of campus operations, laid out in its newsletter just what would be at stake if the university lost hundreds of millions dollars in federal grant money. The society has pushed both for Columbia to take a position of institutional neutrality, as the University of Chicago has done for decades, and to work harder to fight campus antisemitism (so that the university does not “dissipate due to the actions of a violent and nihilistic fringe mob”). It also made a persuasive argument that the disappearance of so much money would be catastrophic.

Reviewing the university’s 2024 financial statements, the writers pointed out that of the $1.3 billion Columbia receives annually from federal agencies, the bulk — $747 million — comes from the National Institutes of Health. About half the money goes to overhead, the cap for which has now been reduced. Whatever visions “overhead” conjures of boondoggle trips to conferences in Prague, much of the money that does not go directly to research covers expenses like salaries, lab renovations, student supports and the administrative work required to comply with federal regulations, 168 of which were adopted over the last decade.

Prestigious universities have come to find adversaries in many worlds, among the working class, among rich alumni, among highly educated progressives who find them self-regarding. “Universities are good targets for resentment,” said Michael Roth, the president of Wesleyan University who has written about modern campus politics. “They take such enormous pride in how many people they reject.

“We at universities have not done enough over the years to pay attention to those groups — conservative groups, religious groups — around the country that are essential parts of a democratic culture. The isolation makes us very vulnerable.”

It has become common in the narrative of the current moment to compare campus upheaval to the disruptions of the late 1960s, but the sense of vindictiveness and distaste directed at the academy now can seem of a different order entirely. In 1968, Richard Nixon — famously hostile to campus radicals, and soon to be president — was asked by an interviewer about the public pressure “to get tough and crack down on the student rebels.”

What, the interviewer wanted to know, was his view of the role of dissent on the college campus? “I’m for it,” Nixon responded. “I’m for dissent, because as I look back at the 190-year history of this country, I find that dissent is the great instrument of change.”

About 150 demonstrators affiliated with a progressive Jewish activist group packed into the lower level of Trump Tower Thursday to protest the arrest of Mahmoud Khalil, a Palestinian activist and former Columbia University student.

President Trump has heralded the arrest as his administration moves to deport Mr. Khalil, a legal permanent resident of the United States who was a prominent figure in pro-Palestinian demonstrations on Columbia’s campus.

The protesters held aloft cloth banners printed in red and black lettering. One read: “Free Mahmoud, Free Palestine.” They chanted, their words reverberating against the coral marble tiling. “Fight Nazis, not students,” they repeated.

Ninety-eight of the protesters were later arrested, according to John Chell, the Police Department’s chief of department.

Since news of Mr. Khalil’s arrest on Saturday became public, New Yorkers have taken to the streets, marching in Lower Manhattan and gathering on Columbia’s campus uptown. Free speech advocates and immigrant rights groups have questioned the legality of arresting Mr. Khalil, 30, who has a green card, was born and raised in Syria and is married to an American citizen. His lawyers are challenging his arrest in court.

Shortly before noon on Thursday, hundreds of people who had slowly been streaming into the lower level plaza of Trump Tower, Mr. Trump’s high-rise in Midtown Manhattan, took off their coats and revealed bright red T-shirts that said “Not in Our Name” on the front and “Jews Say Stop Arming Israel” on the back.

In 2015, Mr. Trump launched his first winning presidential campaign from a lectern in the very same building, after descending the golden escalator into the lobby. One of the protesters, Josh Dubnau, said the symbolism was intentional.

“He came down that escalator and immediately started demonizing immigrants,” said Mr. Dubnau, 59, a professor at Stony Brook University. “And so this is a symbolic spot where we’re here to say ‘no more.’ We won’t tolerate that.”

Building security officers turned up the music in the lobby and stopped more people from joining the group. After about 15 minutes, police officers who had been watching from afar warned that protesters who remained on the premises would be subject to arrest. Some began to slowly stream out; others stayed seated and continued to chant.

Roughly an hour after the protest started, more than two dozen officers began detaining demonstrators, zip-tying their hands behind their backs, lifting them to their feet and carrying them up the escalator.

Below, protesters continued chanting.

“We will not comply,” they said. “Mahmoud, we are by your side.”

White House officials have justified Mr. Khalil’s arrest by suggesting that by organizing protests on Columbia’s campus, he “led activities aligned to Hamas.” Officials have not accused Mr. Khalil of having any contact with Hamas, taking direction from it or providing material support to it.

His arrest marked an escalation of the Trump administration’s efforts to crack down on the protests, which officials have described as antisemitic and a threat to the safety of Jewish students.

The protesters at Trump Tower, many of whom were Jewish, pushed back on that notion.

One of them, Jane Hirschmann, 78, said that she believed Jews had a particular obligation to voice their opposition to the Trump administration because it had “weaponized antisemitism.”

Ms. Hirschmann, the descendant of Holocaust survivors, said Mr. Khalil’s arrest reminded her of family stories from that “terrible time,” when her grandfather and uncle were taken away in the middle of the night.

“I know, personally from my family history, I know what fascism is, I know what genocide is, I know what abduction is,” Ms. Hirschmann said.

Moments later, she was arrested.

James Schamus, a Columbia professor who participated in the protest and is Jewish, said he thought the notion that the campus was “somehow a hotbed of antisemitic intolerance” was ridiculous.

“We all know that if anything, Columbia is a hotbed of students raising their voice and conscience, and in protest against the inhumane policies that this regime is imposing,” he said.

Plans for the event came together in 36 hours, said Sonya Meyerson-Knox, a spokeswoman for Jewish Voice for Peace.

“As Jews, we know our history,” she said. “We know what happens when authoritarian regimes start scapegoating people and start taking away rights; we know exactly where that leads.”
