The federal government says it’s freezing more than $2.2 billion in grants and $60 million in contracts to Harvard University, after the institution said it would defy the Trump administration’s demands to limit activism on campus.

The hold on Harvard’s funding marks the seventh time President Donald Trump’s administration has taken the step at one of the nation’s most elite colleges, in an attempt to force compliance with Trump’s political agenda. Six of the seven schools are in the Ivy League.

It sets the stage for a showdown between the federal government and America’s oldest and wealthiest university. With an endowment of more than $50 billion, Harvard is perhaps the best positioned university to push back on the administration’s pressure campaign.

In a letter to Harvard Friday, Trump’s administration had called for broad government and leadership reforms at the university, as well as changes to its admissions policies. It also demanded the university audit views of diversity on campus, and stop recognizing some student clubs.

The federal government said almost $9 billion in grants and contracts in total were at risk if Harvard did not comply.

On Monday, Harvard President Alan Garber said the university would not bend to the government’s demands.

“The University will not surrender its independence or relinquish its constitutional rights,” Garber said in a letter to the Harvard community. “No government — regardless of which party is in power — should dictate what private universities can teach, whom they can admit and hire, and which areas of study and inquiry they can pursue.”

Hours later, the government froze billions in Harvard’s federal funding.

The first university targeted by the Trump administration was Columbia, which acquiesced to the government’s demands under the threat of billions of dollars in cuts. The administration also has paused federal funding for the University of Pennsylvania, Brown, Princeton, Cornell and Northwestern.

Trump’s administration has normalized the extraordinary step of withholding federal money to pressure major academic institutions to comply with the president’s political agenda and to influence campus policy. The administration has argued universities allowed antisemitism to go unchecked at campus protests last year against Israel’s war in Gaza.

Harvard, Garber said, already has made extensive reforms to address antisemitism. He said many of the government’s demands don’t relate to antisemitism, but instead are an attempt to regulate the “intellectual conditions” at Harvard.

Withholding federal funding from Harvard, one of the nation’s top research universities in science and medicine, “risks not only the health and well-being of millions of individuals but also the economic security and vitality of our nation.” It also violates the university’s First Amendment rights and exceeds the government’s authority under Title VI, which prohibits discrimination against students based on their race, color or national origin, Garber said.

The government’s demands included that Harvard institute what it called “merit-based” admissions and hiring policies and conduct an audit of the study body, faculty and leadership on their views about diversity. The administration also called for a ban on face masks at Harvard — an apparent target of pro-Palestinian campus protesters — and pressured the university to stop recognizing or funding “any student group or club that endorses or promotes criminal activity, illegal violence, or illegal harassment.”

Harvard’s defiance, the federal antisemitism task force said Monday, “reinforces the troubling entitlement mindset that is endemic in our nation’s most prestigious universities and colleges — that federal investment does not come with the responsibility to uphold civil rights laws.

John Gutierrez had been thinking about buying a new laptop for the past year. The Austin, Texas, resident needed a computer with faster processing and increased storage for his photography work and had his sights set on a product from a Taiwanese brand.

Then President Donald Trump announced expansive new import tariffs Wednesday, including a 32% tax on imports from Taiwan. That same day, Gutierrez ordered the laptop, with a base price of $2,400, from a retailer in New York specializing in photo and video gear.

“I thought I’d bite the bullet, buy it now, and then that way I’ll have the latest technology on my laptop and don’t have to worry about the tariffs,” he said.

Gutierrez was among the U.S. consumers rushing to buy big-ticket items before the tariffs take effect. Economists say the tariffs are expected to increase prices for everyday items, warning of potentially weakened U.S. economic growth.

The White House hopes the tariffs prod countries to open their economies to more American exports, leading to negotiations that could reduce tariffs, or that companies increase their production in the U.S. to avoid higher import taxes.

Rob Blackwell and his wife needed a new car that could handle long drives from Arlington, Virginia, to their son’s college. Their current electric vehicle is older with a limited range, and it will soon be used by his daughter, who is on the verge of getting her driver’s license.

“I have been telling my wife that for some time we were going to need to do it,” he said, “and I was watching to see what the president did with tariffs.”

Blackwell wanted another EV, but said leasing made more economic sense because the technology is ever-changing. He had his eye on the new General Motors Optiq; it’s an American car but made in Mexico, which could be subject to tariffs on supply chains that might increase the cost.

After hearing that tariffs would be announced, they made plans the weekend before to lease the car. He said the dealership honored the agreement they worked out before the tariffs were finalized. And although he said the salespeople were a pleasure to deal with, Blackwell sensed a shift in their stance.

A court formally arrested the mayor of Istanbul, a key rival to President Recep Tayyip Erdogan, on Sunday and ordered him jailed pending the outcome of a trial on corruption charges.

Mayor Ekrem Imamoglu was detained following a raid on his residence earlier this week, sparking the largest wave of street demonstrations in Turkey in more than a decade. It also deepened concerns over democracy and rule of law in Turkey.

His imprisonment is widely regarded as a political move to remove a major contender from the next presidential race, currently scheduled for 2028. Government officials reject the accusations and insist that Turkey’s courts operate independently.

The prosecutor’s office said the court decided to jail Imamoglu on suspicion of running a criminal organization, accepting bribes, extortion, illegally recording personal data and bid-rigging. A request for him to be imprisoned on terror-related charges was rejected although he still faces prosecution. Following the court’s ruling, Imamoglu was transferred to Silivri prison, west of Istanbul.

The Interior Ministry later announced that Imamoglu had been suspended from duty as a “temporary measure.” The municipality had previously appointed an acting mayor from its governing council.

Alongside Imamoglu, 47 other people were also jailed pending trial, including a key aide and two district mayors from Istanbul, one of whom was replaced with a government appointee. A further 44 suspects were released under judicial control.

Interior Minister Ali Yerlikaya said Sunday that 323 people were detained the previous evening over disturbances at protests.

Largely peaceful protests across Turkey have seen hundreds of thousands come out in support of Imamoglu. However, there has been some violence, with police deploying water cannons, tear gas, pepper spray and firing plastic pellets at protesters in Istanbul, Ankara and Izmir, some of whom hurled stones, fireworks and other missiles at riot police.

The formal arrest came as more than 1.5 million members of the opposition Republican People’s Party, or CHP, began holding a primary presidential election to endorse Imamoglu, the sole candidate.

The party has also set up symbolic ballot boxes nationwide to allow people who are not party members to express their support for the mayor. Large crowds gathered early Sunday to cast a “solidarity ballot.”

“This is no longer just a problem of the Republican People’s Party, but a problem of Turkish democracy,” Fusun Erben, 69, said at a polling station in Istanbul’s Kadikoy district. “We do not accept our rights being so easily usurped. We will fight until the end.”

Speaking at a polling station in Bodrum, western Turkey, engineer Mehmet Dayanc, 38, said he feared that “in the end we’ll be like Russia, a country without an opposition, where only a single man participates in elections.”

In a message posted on social media, Imamoglu called on people to show “their struggle for democracy and justice to the entire world” at the ballot box. He warned Erdogan that he would be defeated by “our righteousness, our courage, our humility, our smiling face.”

“Honestly, we are embarrassed in the name of our legal system,” Ankara Mayor Mansur Yavas, a fellow member of Imamoglu’s CHP, told reporters after casting his vote, criticizing the lack of confidentiality in the proceedings.

CHP leader Ozgur Ozel said Imamoglu’s imprisonment was reminiscent of “Italian mafia methods.” Speaking at Istanbul City Hall, he added: “Imamoglu is on the one hand in prison and on the other hand on the way to the presidency.”

The Council of Europe, which focuses on promoting human rights and democracy, slammed the decision and demanded Imamoglu’s immediate release.

Under threat from the Trump administration, Columbia University agreed to implement a host of policy changes Friday, including overhauling its rules for protests and conducting an immediate review of its Middle Eastern studies department.

The changes, detailed in a letter sent by the university’s interim president, Katrina Armstrong, came one week after the Trump administration ordered the Ivy League school to enact those and other reforms or lose all federal funding, an ultimatum widely criticized in academia as an attack on academic freedom.

In her letter, Armstrong said the university would immediately appoint a senior vice provost to conduct a thorough review of the portfolio of its regional studies programs, “starting immediately with the Middle East.”

Columbia will also revamp its long-standing disciplinary process and bar protests inside academic buildings. Students will not be permitted to wear face masks on campus “for the purposes of concealing one’s identity.” An exception would be made for people wearing them for health reasons.

In an effort to expand “intellectual diversity” within the university, Columbia will also appoint new faculty members to its Institute for Israel and Jewish Studies department. It will also adopt a new definition of antisemitism and expand programming in its Tel Aviv Center, a research hub based in Israel.

The policy changes were largely in line with demands made on the university by the Trump administration, which pulled $400 million in research grants and other federal funding, and had threatened to cut more, over the university’s handling of protests against Israel’s military campaign in Gaza.

The White House has labeled the protests antisemitic, a label rejected by those who participated in the student-led demonstrations.

A message seeking comment was left with a spokesperson for the Education Department. As a “precondition” for restoring funding, federal officials demanded that the university to place its Middle Eastern, South Asian and African Studies Department under “academic receivership for a minimum of five years.”

Historians had described the order as an unprecedented intrusion on university rights long treated by the Supreme Court as an extension of the First Amendment.

On Friday, freedom of speech advocates immediately decried Columbia’s decision to acquiesce.

Hundreds of thousands of federal workers have been given little more than 48 hours to explain what they accomplished over the last week, sparking confusion across key agencies as billionaire Elon Musk expands his crusade to slash the size of federal government.

Musk, who serves as President Donald Trump’s cost-cutting chief, telegraphed the extraordinary request on his social media network on Saturday.

“Consistent with President @realDonaldTrump’s instructions, all federal employees will shortly receive an email requesting to understand what they got done last week,” Musk posted on X, which he owns. “Failure to respond will be taken as a resignation.”

Shortly afterward, federal employees — including some judges, court staff and federal prison officials — received a three-line email with this instruction: “Please reply to this email with approx. 5 bullets of what you accomplished last week and cc your manager.”

The deadline to reply was listed as Monday at 11:59 p.m., although the email did not include Musk’s social media threat about those who fail to respond.

The latest unusual directive from Musk’s team injects a new sense of chaos across beleaguered multiple agencies, including the National Weather Service, the State Department and the federal court system, as senior officials worked to verify the message’s authenticity Saturday night and in some cases, instructed their employees not to respond.

Thousands of government employees have already been forced out of the federal workforce — either by being fired or offered a buyout — during the first month of Trump’s administration as the White House and Musk’s so-called Department of Government Efficiency fire both new and career workers, tell agency leaders to plan for “large-scale reductions in force” and freeze trillions of dollars in federal grant funds.

There is no official figure available for the total firings or layoffs so far, but The Associated Press has tallied hundreds of thousands of workers who are being affected. Many work outside of Washington. The cuts include thousands at the Departments of Veterans Affairs, Defense, Health and Human Services, the Internal Revenue Service and the National Parks Service, among others.

Labor union leaders quickly condemned the ultimatum and threatened legal action.

AFGE President Everett Kelley called the new order an example of Trump and Musk’s “utter disdain for federal employees and the critical services they provide to the American people.”

“It is cruel and disrespectful to hundreds of thousands of veterans who are wearing their second uniform in the civil service to be forced to justify their job duties to this out-of-touch, privileged, unelected billionaire who has never performed one single hour of honest public service in his life,” Kelley said. “AFGE will challenge any unlawful terminations of our members and federal employees across the country.”

Musk on Friday celebrated his new role at a gathering of conservatives by waving a giant chainsaw in the air. He called it “the chainsaw for bureaucracy” and said, “Waste is pretty much everywhere” in the federal government.

McLaurine Pinover, a spokesperson at the Office of Personnel Management, confirmed Musk’s directive and said that individual agencies would “determine any next steps.”

What happens if an employee is on leave or vacation? Again, she said individual agencies would determine how to proceed.

In a message to employees on Saturday night, federal court officials instructed recipients not to respond.

“We understand that some judges and judiciary staff have received an email ... directing the recipient to reply with 5 accomplishments from the prior week. Please be advised that this email did not originate from the Judiciary or the Administrative Office and we suggest that no action be taken,” officials wrote.

Judges around the country got emails from Musk’s team in late January, apparently by mistake, U.S. District Judge Randolph Daniel Moss said earlier this month. Moss said he’d also gotten a message and ignored it.

The National Weather Service leadership acknowledged some confusion in a message to its employees late Saturday as well.
