U.S. immigration officials have detained several pro-Palestinian activists at Columbia University, including prominent student leader Mahmoud Khalil, who has been a vocal figure in recent protests against Israeli policies. Khalil, a green card holder, was arrested by ICE despite his legal status, prompting outcry from fellow students and activists, who argue that his detention threatens free speech rights on campus. In response to these arrests, students have vowed to continue their protests, escalating their calls for solidarity and support against immigration authorities. The situation has led to heightened security measures at the university as advocates mobilize against what they describe as a concerted effort to suppress dissenting voices. Notably, prominent political figures, including Marco Rubio, have endorsed stronger immigration enforcement actions, further complicating the climate for student activists.
