A Cornell University student who participated in pro-Palestinian protests is leaving the United States due to fear of detention and threats to his personal safety. The student, Momodou Taal, had been asked to surrender by U.S. immigration officials and had his student visa revoked. President Donald Trump has threatened to deport foreign pro-Palestinian protesters, accusing them of supporting Hamas and posing foreign policy hurdles. Taal's departure comes as other pro-Palestinian activists at Columbia University and Georgetown University face legal challenges and potential deportation.
