The Trump administration is tightening its grip on efforts to quash pro-Palestinian demonstrations on college campuses, even as a protest over the detention of activist Mahmoud Khalil flared at the president’s New York City residence and resistance efforts continue in the courts and beyond.

Nearly 100 protesters arrested after sit-in at Trump Tower in NYC to demand release of Mahmoud Khalil. Khalil became one of the faces of the protests against Israel at Columbia University last spring and now faces possible deportation.
