Columbia activist Mahmoud Khalil arrested by federal authorities

Mahmoud Khalil, a Palestinian activist and Columbia University student, was arrested by federal immigration authorities on Saturday. His attorney claims the arrest was based on a State Department order to revoke his green card. A federal judge has temporarily blocked Khalil's deportation until a court conference on Wednesday. Khalil's arrest follows President Trump's crackdown on pro-Palestinian protests, with the administration targeting activists involved in demonstrations against Israel's actions in Gaza. Khalil is currently held in a Louisiana detention facility. His arrest has sparked protests and criticism from civil rights groups, who argue it infringes on free speech rights and is part of a broader effort to suppress dissent against U.S. foreign policy.
