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.

President Donald Trump is warning that the arrest and possible deportation of a Palestinian activist who helped lead protests at Columbia University will be the first “of many to come” as his administration cracks down on protests against the war in Gaza.
