Columbia University protestor Mahmoud Khalil detained in Louisiana

Mahmoud Khalil, a 29-year-old legal resident and Palestinian activist, was arrested by federal agents after his green card was revoked by the Trump administration. He was detained in Louisiana, with a federal judge blocking immediate deportation. Khalil, who recently completed his master's degree at Columbia University, has been involved in pro-Palestinian activism. His attorney claims his arrest is an attempt to suppress lawful dissent, while the Trump administration views his actions as supportive of terrorism. Protests have erupted in response to Khalil's detention, with over 1.7 million people signing a petition for his release. Supporters argue that his arrest violates First Amendment rights, while some groups praise the administration's actions against perceived antisemitism on college campuses.
