WASHINGTON (TNND) — The Trump administration plans to cancel $100 million of the federal government's remaining federal contracts with Harvard and "find alternative vendors" for future services, according to a letter sent on Tuesday.

In the letter obtained by The New York Times, an administration official called it a "complete severance of the government’s longstanding business relationship with Harvard."

Agencies are instructed to respond by June 6 with a list of contract cancellations, according to the letter.

It is the latest move in the ongoing Trump-Harvard feud after the Ivy League partially denied Homeland Security Secretary Kristy Noem's request for private student data, including international students.

President Donald Trump posted about the issue on Monday, writing, "We are still waiting for the Foreign Student Lists from Harvard so that we can determine, after a ridiculous expenditure of BILLIONS OF DOLLARS, how many radicalized lunatics, troublemakers all, should not be let back into our Country. Harvard is very slow in the presentation of these documents, and probably for good reason!"

In response to Harvard's delay in providing the requested information, the Department of Homeland Security revoked the university's ability to admit international students. However, an Obama-appointed federal judge temporarily blocked this action, leaving the situation unresolved.

Harvard told The National News Desk (TNND) it believes the move violates the law.

"The government’s action is unlawful.," a spokesperson wrote via email "We are fully committed to maintaining Harvard’s ability to host international students and scholars, who hail from more than 140 countries and enrich the University – and this nation – immeasurably. We are working quickly to provide guidance and support to members of our community. This retaliatory action threatens serious harm to the Harvard community and our country, and undermines Harvard’s academic and research mission.”

On Monday, President Donald Trump threatened to redirect $3 billion in federal grants from the university to trade schools.

The administration also previously froze $2.2 billion in grants, citing concerns over antisemitism on campus.

The university has accused Trump of violating its First Amendment rights and of trying to control its curriculum, faculty and student body.
