Columbia student faces deportation over free speech issues

Mahmoud Khalil, a permanent resident and Columbia University graduate, faces deportation amid accusations of supporting terrorism. A judge will review constitutional issues related to his case on Wednesday. Judge Jesse Furman has ordered the government to halt Khalil's removal while the case is ongoing. Khalil was arrested after leading protests against Israel's actions in Gaza. Khalil's lawyers argue his detention is retaliation for exercising free speech. They seek his return to New York to be with his pregnant wife, an American citizen.
