Harvard’s leadership has asked a court to stop the Trump administration’s latest attempt to block international students — over a fourth of its student body — from coming to the university, according to a new court filing less than 24 hours after the latest move by President Donald Trump against the university.

President Donald Trump has gone after the world’s wealthiest higher education institution in the name of antisemitism, claiming Harvard has failed to protect Jewish students, particularly in the wake of the war in Gaza.

Harvard University has filed a lawsuit against the Trump administration. The suit challenges a proclamation that suspends new international student visas. Harvard argues the proclamation is retaliatory and violates academic freedom.
