Marco Rubio can declare protester Mahmoud Khalil deportable

The Trump administration has arrested Mahmoud Khalil, a pro-Palestinian protester and permanent resident, using a rare provision of immigration law. Secretary of State Marco Rubio can declare Khalil deportable, but the administration must prove he poses a foreign policy threat in court. Khalil's arrest follows his involvement in protests at Columbia University. The administration claims his presence could harm U.S. foreign policy, but legal experts suggest proving this will be challenging. Khalil is entitled to due process, and a federal judge has blocked his immediate deportation. Khalil's case may set a precedent for future actions against non-citizen protesters. The administration's approach has drawn criticism, with civil rights groups arguing it infringes on free speech rights. Khalil's legal proceedings could take years, but a bond hearing may occur soon.
