A prominent Palestinian activist who helped lead last spring’s protests at Columbia University is facing deportation following his arrest by federal immigration agents over the weekend.

The move comes days after the Trump administration announced it was pulling $400 million in funding from Columbia University.

President Donald Trump promised last week to round up the "agitators" responsible for "illegal protests" on college campuses. Over the weekend, his administration claimed its first scalp: Mahmoud Khalil, a lead negotiator for pro-Palestinian protest camp at Columbia University.
