Jewish protesters filled the lobby of Trump Tower to denounce the immigration arrest of a Columbia University activist who led student protests against Israel's war in Gaza. The protesters, from the group Jewish Voice for Peace, chanted 'Bring Mahmoud home now!' and were eventually arrested by police. The activist, Mahmoud Khalil, a permanent U.S. resident, was arrested and faces deportation. President Trump has vowed to deport students engaged in 'pro-terrorist, anti-Semitic, anti-American activity.' Khalil's supporters argue that his arrest is an attack on free speech.
