Columbia activist detained 104 days without warrant, later sues over deportation effort
Mahmoud Khalil, a Syrian-Palestinian lawful permanent resident and Columbia University graduate student known for organizing pro-Palestinian campus protests, was arrested by ICE agents at his student housing in March 2025 with no prior notice. Agents initially claimed his student visa had been revoked, then arrested him anyway after he showed proof of his green card, alleging without explanation that his residency status had also been revoked. His wife, a U.S. citizen, was eight months pregnant at the time. Khalil filed a habeas corpus petition arguing the arrest violated his First Amendment and Due Process rights, accusing the government of using immigration enforcement to suppress student activism. The Trump administration sought his deportation, citing his prior employment with a UN Palestinian refugee agency and invoking a provision allowing removal of noncitizens deemed a foreign policy threat. Khalil was held 104 days at Louisiana's LaSalle Detention Center; a federal appellate court later reversed an earlier release order. After an immigration board denied his appeal in July 2026, Khalil sued Trump administration officials and pro-Israel groups, alleging a coordinated campaign to target pro-Palestinian activists.
