Trump warns of crackdown on pro-Palestinian activism

Mahmoud Khalil, a Palestinian activist and former Columbia University student, was arrested by immigration agents in New York. His lawyer claims the government is revoking his green card, marking a significant action under President Trump's crackdown on campus protests against Israel. Khalil's detention has sparked outrage from civil rights groups, who argue it targets free speech. A federal judge has ordered that he not be deported while his case is reviewed, with a hearing set for Wednesday. The Trump administration has warned universities they could lose federal funding if they do not ensure safety for Jewish students. This follows Khalil's arrest, which is seen as the first under the new enforcement policy against pro-Palestinian activism.
