Federal court hears case of detained Columbia student

A federal court in Manhattan will hear arguments on Wednesday regarding the detention of Mahmoud Khalil, a Columbia University graduate student. Khalil was arrested by immigration agents and is facing deportation due to his involvement in pro-Palestinian protests. Khalil's lawyers argue that his actions are protected free speech and that the government is retaliating against him. A judge has temporarily halted his deportation while the case is considered. Protests in support of Khalil have occurred in New York City, with some arrests made during demonstrations. Khalil, a permanent U.S. resident, has not been charged with any crime.
