Rubio Revokes Visas in 'Catch and Revoke' Effort

US Secretary of State Marco Rubio announced the revocation of over 300 visas for foreign nationals involved in pro-Palestinian protests at US universities, labeling them as 'lunatics'. The Trump administration's 'Catch and Revoke' effort uses AI to identify individuals supporting organizations like Hamas through social media, sparking controversy and concerns over potential abuse. One high-profile case involves Rumeysa Ozturk, a Turkish doctoral student at Tufts University, whose visa was revoked due to alleged pro-Hamas activities, though no formal charges have been filed against her. The administration's actions have raised questions about free speech rights for non-citizens, as critics argue the measures are a slippery slope. Rubio has defended the crackdown, citing national security and the prevention of campus disruptions as justifications.
