President Donald Trump publicly demanded $1 billion from Harvard University as part of a prolonged dispute that has included federal funding cuts and litigation over allegations of antisemitism. Trump said the university had been 'behaving very badly' and raised the amount after earlier reports he had eased financial demands. Harvard has rejected direct payment to the government and has litigated funding cuts, winning a December court reversal. The escalating standoff has immediate consequences for research funding and university relations with the federal government: the administration previously reduced billions in grants and attempted to press policy changes on foreign students and campus speech. Legal experts say the conflict raises questions about executive leverage over federal research dollars and the precedent of conditioning funding on political demands.
