ICE arrests Palestinian leader of Columbia's anti-Israel protests, revoking student visa and green card - lawyer | 9 March 2025 | President Trump is giving this anti-Israel campus rabble-rouser a ticket to study aboard -- for good. A Palestinian activist who led the disruptive protests at both Columbia University and Barnard College has been arrested by ICE agents at his campus apartment, according to his lawyer. Mahmoud Khalil, who completed his graduate studies at Ivy League Columbia in December, also potentially faces having his visa revoked and his green card canceled following President Trump's crackdown on unrest at colleges, attorney Amy Greer said Sunday. He was inside his university-owned apartment a few blocks from campus Saturday night when ICE agents entered the residence and took him into custody, Greer said.
