The Trump administration mistakenly sent a letter of demands to Harvard University, which led to the freezing of federal funding and threats to the university's tax-exempt status. The letter, sent by the administration's task force on antisemitism, was unauthorized and not meant to be sent, according to multiple sources. Harvard had been in talks with the task force about revising its practices, but the demands outlined in the letter made reaching an agreement with the administration impossible. The administration claims that Harvard's lawyers should have contacted the task force before rejecting the demands, and is seeking an apology from the university.
