Palestinian activist Khalil detained over Columbia protests

Mahmoud Khalil, a 29-year-old Palestinian activist and legal U.S. resident, was arrested by federal agents after his green card was revoked by the Trump administration. He was involved in pro-Palestinian protests at Columbia University. A federal judge has temporarily blocked Khalil's deportation and scheduled a hearing for Wednesday. His attorney claims the arrest violates his First Amendment rights, while the Trump administration views Khalil's activism as supportive of Hamas. Khalil's arrest has sparked protests, with over 1.7 million people signing a petition for his release. Supporters argue it represents a broader issue of free speech, while some groups commend the administration's actions against antisemitism on college campuses.
