Mahmoud Khalil Sues Columbia University Over Discrimination 2026

Mahmoud Khalil has sued Columbia University, accusing the institution of years of anti-Palestinian discrimination, indifference to harassment, and retaliation. The lawsuit, announced on Monday, marks a significant escalation in the ongoing debate over free speech and campus treatment of pro-Palestinian advocates.

Who Is Mahmoud Khalil?

Khalil, a US green card holder of Palestinian descent, was a graduate student at Columbia’s School of International and Public Affairs (SIPA). In March 2025, he was arrested at his university apartment by federal immigration agents—the first of several foreign nationals detained by the Trump administration over pro-Palestinian advocacy. He missed the birth of his first son while in detention but was released in June 2025. He continues to fight deportation efforts, a battle expected to reach the US Supreme Court.

Details of the Lawsuit Against Columbia University

The 60-page complaint, filed in the Southern District of New York, names the university, its board, and SIPA dean Keren Yarhi-Milo. Khalil and members of SIPA’s Palestine Working Group allege “deliberate indifference” and failure to address “severe, persistent, and coordinated harassment” targeting students outspoken about Palestinian rights.

Key Allegations

• Anti-Palestinian discrimination: A years-long pattern of unequal treatment.
• Indifference to harassment: University failed to protect students from coordinated attacks.
• Retaliation: Punitive actions against Khalil and others for their advocacy.

Columbia University’s Response and Legal Context

Columbia University has not yet issued a detailed public response. The lawsuit adds to mounting legal scrutiny over how universities handle discrimination and free speech, particularly regarding Palestinian rights. Khalil’s case is intertwined with his separate lawsuit against the Trump administration over his detention, raising complex questions about immigration law and First Amendment protections.
