Columbia protest leader detained after Trump's deportation pledge

A leader of pro-Palestinian protests at Columbia University, Mahmoud Khalil, was detained by immigration officers after President Trump pledged to deport foreign demonstrators. Khalil, a recent graduate, was a key figure in the campus protests against Israel's actions in Gaza. The Student Workers of Columbia union reported that Khalil was arrested on Saturday. He held permanent residency at the time, prompting a petition for his release. The union also noted increased ICE activity on campus. Trump's administration has cut $400 million in federal grants to Columbia, citing inadequate protection for Jewish students. The university stated it complies with legal requirements regarding law enforcement access to campus buildings.
