Federal agents arrested Palestinian activist Mahmoud Khalil

Federal immigration agents arrested Mahmoud Khalil, a Palestinian activist and former Columbia University student, at his apartment on Saturday. His lawyer stated that agents claimed they were acting on orders to revoke his student visa, later switching to his green card. Khalil's arrest is the first known deportation effort under the Trump administration's crackdown on student activists involved in protests against Israel. The Department of Homeland Security linked his arrest to allegations of supporting Hamas, a designated terrorist organization. Khalil's detention has raised concerns among immigration experts, who view it as a retaliatory action against his activism. He is under investigation by Columbia University for his involvement in pro-Palestinian activities, which has led to disciplinary charges against several students.
