Dozens protest the detention of Mahmoud Khalil outside Milwaukee federal courthouse

MILWAUKEE (CBS 58) -- There was a protest on Friday, March 14 outside the federal courthouse in Milwaukee. 

The demonstration was a response to the arrest of Mahmoud Khalil, the Palestinian refugee helped lead Columbia University's encampment protest last year. 

Right now, he is being detained by ICE and has had his green card revoked. 

This, as the White House cracks down on recent pro-Palestinian demonstrations on college campuses, something critics say is an attempt to silence protesters. 

"This really sets a very, very dangerous precedent," said Janan Najeeb, Wisconsin Coalition for Justice in Palestine. "But this is not going to phase us we're going to continue to come out, we're going to continue to march, and we are going to protect our democracy and our rights."

The Trump administration is also accusing more than 60 universities of failing to address antisemitism during last year's pro-Palestinian encampments. That includes UW-Madison, which could be targeted by federal funding cuts in response.
