The Trump administration plans to ask all federal agencies to explore ways to end their contracts with Harvard University, a senior administration official told NBC News on Tuesday.

“GSA will send a letter to federal agencies today asking them to identify any contracts with Harvard, and whether they can be canceled or redirected elsewhere,” the official said, referring to the General Services Administration.

This development was first reported by The New York Times.

These proposed contract terminations mark the latest escalation in a months-long dispute between the Trump administration and Harvard, one of the nation’s oldest and most prestigious universities.

A copy of the letter obtained by NBC News instructs agencies to provide the GSA with a list of any contracts they have ended with Harvard by June 6.

“Going forward, we also encourage your agency to seek alternative vendors for future services where you had previously considered Harvard,” the letter reads. It is signed by John Gruenbaum, commissioner of the GSA’s Federal Acquisition Service.

Gruenbaum described the administration’s actions as an effort to uphold civil rights, accusing Harvard of defying a Supreme Court ruling that banned the consideration of race in admissions and of “ongoing inaction” over harassment of its Jewish students.

Harvard did not immediately respond to requests for comment.

The directive comes a day after former President Trump posted on Truth Social that he was considering redirecting $3 billion in grant money away from what he called “a very anti-Semitic” Harvard, and instead awarding it to trade schools.

The conflict between the government and Harvard largely stems from the university’s refusal to comply with demands from the Trump administration’s Task Force to Combat Anti-Semitism. The task force sought to review Harvard’s admissions and hiring policies and to audit its faculty.

In response, the administration cut $2 billion in federal research funding to Harvard.

Last week, the administration also tried to block Harvard from enrolling foreign students, a move temporarily halted by a federal judge after Harvard filed a lawsuit. A hearing on whether to extend the judge’s order is scheduled for Thursday.

If the administration’s efforts succeed, foreign students at Harvard—who make up about a quarter of its student body—would lose their legal status to remain in the United States or would need to transfer to other universities.
