Mahmoud Khalil, a Palestinian activist and former Columbia University graduate student, has been engaged in a legal battle regarding his immigration status in the United States. After being apprehended by federal agents in March 2025, Khalil was released from immigration detention following 104 days of incarceration.

His legal team, supported by the American Civil Liberties Union and the Center for Constitutional Rights, is petitioning the Supreme Court to overturn a deportation order on constitutional grounds. Despite his release, Khalil remains under threat of deportation by the Trump administration. Following his release, Khalil faced renewed calls for deportation after an interview with CNN, where he declined to condemn Hamas, characterizing questions about the group as ‘silly’ and ‘disingenuous.’

In October 2026, Khalil petitioned the U.S. Supreme Court to prevent his re-arrest following a ruling by the 3rd U.S. Circuit Court of Appeals. The appellate court held that federal courts lack jurisdiction to review the legality of immigration-related detentions until immigration court proceedings are fully completed. Khalil’s legal team argues this prevents noncitizens from seeking immediate judicial oversight via habeas corpus petitions to challenge detentions they claim are retaliatory for protected First Amendment speech. 

In response to the appellate ruling, Khalil has filed an emergency application with the Supreme Court. The Trump administration has defended its actions, with the Department of Homeland Security stating it acted within its statutory authority. Furthermore, a White House spokeswoman alleged that Khalil failed to accurately report background information during his visa and green card applications, specifically regarding his work with the UN Relief and Works Agency (UNRWA). Secretary of State Marco Rubio previously signed a determination stating that Khalil’s activities compromised U.S. foreign policy interests. Khalil remains free pending the Supreme Court's decision.
