Columbia University protest leader Mahmoud Khalil will remain detained at an Immigration and Customs Enforcement facility in Louisiana, multiple outlets reported. The big picture: U.S. District Judge Jesse M.

Agents told Mahmoud Khalil’s attorney that they were revoking Khalil’s green card. He is legally considered a permanent resident.

The 12 protesters were taken into custody as scores of people rallied outside City Hall Park in lower Manhattan Tuesday evening.
