Harvard sweatshirts are displayed for sale in a school store window on the Harvard University campus in Cambridge, Massachusetts, on April 15, 2025. US President Donald Trump's administration on Thursday revoked Harvard's right to enroll foreign students -- more than a quarter of its annual enrollment -- in a major escalation of the president's fight with one of the world's most storied universities. Trump is furious at Harvard -- which has produced 162 Nobel prize winners -- for rejecting his demand that it submit to oversight on admissions and hiring over his claims that it is a hotbed of anti-Semitism and "woke" liberal ideology.
