The Trump administration revoked Harvard University's ability to enroll international students in its escalating battle with the Ivy League school, saying thousands of current students must transfer to other schools or leave the country. The Department of Homeland Security announced the action Thursday, saying Harvard has created an unsafe campus environment by allowing “anti-American, pro-terrorist agitators” to assault Jewish students on campus. It also accused Harvard of coordinating with the Chinese communist party, saying it hosted and trained members of a Chinese paramilitary group as recently as 2024.
