The Trump administration has canceled $400 million in federal grants and contracts to Columbia University, citing the school's failure to protect Jewish students from harassment. The administration's targeting of Columbia began after protests last year over the war in Gaza sparked a nationwide debate over free speech, campus policing, and antisemitism. The funding cuts were announced by four federal agencies, and additional cancellations are expected to follow. Columbia currently holds over $5 billion in federal grant commitments and is also facing three federal investigations into allegations of antisemitism on campus.
