Columbia protest leader Mahmoud Khalil detained by immigration

Mahmoud Khalil, a leader of pro-Palestinian protests at Columbia University, was detained by immigration officers on Saturday. His arrest follows President Donald Trump's pledge to deport foreign students involved in similar demonstrations. Khalil, a recent graduate and permanent resident, is currently in immigration detention. His arrest has sparked a petition for his release, with reports of immigration agents attempting to access campus buildings. Columbia University stated it will comply with the law regarding law enforcement access to campus areas. The Trump administration recently cut $400 million in federal grants to Columbia, citing insufficient protection for Jewish students amid rising tensions.
