Prominent Palestinian activist Mahmoud Khalil will remain in an ICE detention facility in Louisiana for now following a procedural hearing in New York, days after he was arrested by federal officials at his Columbia University residence in an attempt by the Trump administration to deport him.

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

Khalil's arrest is the first known deportation effort under Trump’s promised crackdown on students who protested the war in Gaza.
