The United States Department of Homeland Security said Harvard University will lose its ability to enroll foreign students if it does not meet demands from the Trump administration to share information on some visa holders, marking the government's latest escalation against the educational institution.
Department of Homeland Security Secretary Kristi Noem also announced on Wednesday the termination of two DHS grants totalling more than $2.7 million to Harvard.
Noem said she wrote a letter to Harvard demanding records on what she called the "illegal and violent activities" of Harvard's foreign student visa holders by April 30.
"And if Harvard cannot verify it is in full compliance with its reporting requirements, the university will lose the privilege of enrolling foreign students," Noem said in a statement.
A Harvard spokesperson said the university was aware of Noem's letter "regarding grant cancellations and scrutiny of foreign student visas."
The spokesperson said the university stood by its statement earlier in the week to "not surrender its independence or relinquish its constitutional rights" while saying it will comply with the law.
President Donald Trump's administration has threatened universities with federal funding cuts over pro-Palestinian campus protests.
The authorities are also attempting to deport some foreign protesters and have revoked hundreds of visas across the country.
"With a $53.2 billion endowment, Harvard can fund its own chaos - DHS won't," Noem said, adding an "anti-American, pro-Hamas ideology" existed at Harvard.
Harvard has previously said it worked to fight antisemitism and other prejudice on its campus while preserving academic freedoms and the right to protest.
The Trump administration said late last month it was reviewing $9 billion in federal contracts and grants to Harvard and later called for restrictions — including a mask ban and removal of diversity, equity and inclusion programmes — to be put in place for the university to continue receiving federal money.
On Monday, Harvard rejected numerous demands that it said would cede control to the government. The Trump administration subsequently said it was freezing $2.3 billion in funding.
Trump also threatened on Tuesday to strip Harvard of its tax-exempt status. CNN reported on Wednesday the US Internal Revenue Service was making plans to rescind the tax-exempt status of Harvard and that a final decision was expected soon.
Harvard said there was no legal basis to rescind its tax-exempt status, saying such an action would be unprecedented, would diminish its financial aid for students and would lead to abandonment of some critical medical research programmes.
Human rights advocates have raised free speech and academic freedom concerns over the crackdown by the government.
The Trump administration has frozen or cancelled some funding for universities like Columbia, Princeton, Brown, Cornell and Northwestern as well.
It has also threatened to withhold funding over culture war issues such asdiversity, equity and inclusion (DEI) programmes and transgender policies.
