Lawyers for Mahmoud Khalil, a Columbia University student, are expected to appear in a New Jersey court as they fight for his release from federal custody. Khalil, a legal U.S. resident married to an American citizen, was arrested and flown to an immigration detention center in Louisiana. The Trump administration wants to deport Khalil due to his role in campus protests against Israel, which they claim amounted to antisemitic support for Hamas. Other university students and faculty across the country have also faced immigration issues for expressing support for Palestinians.
