U.S. arrests Palestinian activist over protest involvement

U.S. immigration agents arrested Palestinian activist Mahmoud Khalil on March 9, 2025, at his Columbia University apartment. This marks a significant escalation in the Trump administration's efforts to deport student activists involved in protests against Israel. Khalil's attorney stated that ICE agents acted on orders from the State Department to revoke his green card, despite his legal permanent resident status. The arrest is linked to his participation in protests and allegations of supporting Hamas. Columbia University confirmed that law enforcement must have a warrant to enter campus property but did not clarify if one was obtained. Khalil's detention has raised concerns among immigration experts about its legal basis and implications for free speech.
