The Trump administration is seeking to prevent the release of students at Tufts University and Columbia University who were arrested after engaging in pro-Palestinian advocacy on campus. The administration urged a U.S. appeals court to allow immigration authorities to continue to detain the students, Rumeysa Ozturk and Mohsen Mahdawi, despite lower-court orders for Ozturk to be transferred to Vermont for a bail hearing and for Mahdawi to be released.
