Judge to hear student protester's arrest challenge in New York

A U.S. judge will hold a hearing on Wednesday regarding Columbia University student Mahmoud Khalil's challenge to his arrest by immigration authorities. Khalil, a permanent resident, was detained by Homeland Security agents outside his residence. The judge temporarily blocked Khalil's deportation, but the case raises questions about free speech and alleged support for terrorist groups. Khalil's lawyers argue his arrest violated his First Amendment rights, while the Trump administration has accused him of supporting Hamas without presenting evidence. Khalil's arrest has sparked protests in New York City, with several demonstrators arrested. His lawyers are also seeking to have him returned to New York from immigration detention in Louisiana, where access to him has been limited.
