NEW YORK (AP) — The Trump administration has delivered an extraordinary ultimatum to Columbia University, threatening to permanently end federal funding to the school unless it cedes control of an international studies department and implements sweeping changes to other campus policies.

The Trump administration on Thursday pressured Columbia University to make several major reforms, describing its demands as a “precondition” for potentially restoring the university’s federal funding,

Columbia University must take a series of “critical next steps” if it wants to restore $400 million in federal funding, the Trump administration said in a letter to the school, according to The Free Press.
