Columbia University must give detained activist Mahmoud Khalil and other students 30 days' notice before handing over any more documents to Congress as it investigates antisemitism on college campuses, a federal judge in New York ruled Friday. Instead, the Manhattan judge said the student could amend their request for a temporary restraining order and refile it if they address certain issues raised in court. U.S. Rep. Tim Walberg, a Michigan Republican who chairs the House Education and Workforce Committee, called the decision a “victory for credible oversight."
