The Columbia University graduate student was detained by federal immigration agents on March 8 as part of President Donald Trump’s crackdown on what he calls antisemitic and “anti-American” campus protests. Khalil served as a spokesperson and negotiator last year for pro-Palestinian demonstrators who opposed Israel’s military campaign in Gaza.

A U.S. judge on Wednesday extended his order blocking federal authorities from deporting a detained Columbia University student Mahmoud Khalil.

The Department of Homeland Security claimed that Columbia University anti-Israel activist Mahmoud Khalil “led activities aligned to Hamas, a designated terrorist organization."
