Justice Department probes Columbia University over visa issues

The U.S. Justice Department is investigating Columbia University for allegedly hiding illegal immigrants amid a crackdown on foreign students involved in pro-Palestinian protests. This follows recent searches of university residences by Homeland Security agents. One student, Ranjani Srinivasan, left the U.S. after her visa was revoked for alleged advocacy of violence. Another, Leqaa Kordia, was arrested for overstaying her visa, though Columbia claims she was never a student there. The investigation comes as the Trump administration has canceled $400 million in federal funding to Columbia, citing insufficient action against anti-Israel protests. The situation escalated after the arrest of Mahmoud Khalil, a prominent activist, raising concerns about his treatment and the impact on his family.
