A Louisiana immigration judge is set to decide Friday whether to release Palestinian activist and Columbia University student Mahmoud Khalil one month after he was arrested by federal agents following a deportation order from the Trump administration.

JENA, La. (AP) — A Louisiana immigration judge ruled Friday that the U.S. can deport Columbia University graduate student Mahmoud Khalil based on the federal government’s argument that he poses a national security risk. Immigration Judge Jamee Comans made the determination at the end of a nearly two-hour hearing. Khalil can appeal the ruling.
