Mahmoud Khalil sues Columbia University citing ‘hostile environment’ for pro-Palestinian students

(New York Jewish Week) — Mahmoud Khalil, the Palestinian Columbia University alum who was detained by the Trump administration last year, is suing his alma mater along with an Israeli dean of the school he attended for facilitating a “hostile environment” for pro-Palestinian students.

Khalil became a national symbol of the campus pro-Palestinian protest movement when he was detained in March 2025 after the government accused him of being aligned with terrorists. On Monday, he filed a civil rights lawsuit in federal court accusing the school of engaging in months-long “deliberate indifference” toward the harassment of pro-Palestinian students on campus, including at the hands of right-wing pro-Israel groups. 

He contends that Columbia’s alleged indifference ultimately helped to lead to his 104-day detention by federal immigration authorities, during which he missed the birth of his first child, before being released after a federal judge ruled his detainment was likely unconstitutional. He is joined in the suit by members of the School of International and Public Affairs Palestine Working Group, a pro-Palestinian student group on campus.

“Columbia laid the groundwork for my targeting by the Trump administration through its deliberate indifference and discrimination aimed at intimidating Palestinian students,” Khalil told reporters at a press conference in New York on Monday.

In addition to the university, the suit also names Keren Yarhi-Milo, the dean of the Columbia School of International and Public Affairs, who is Israeli-American, as a defendant. The complaint says that Yahi-Milo had unfairly accused Khalil, while a student in the school, of antisemitism and harassment.

In a statement to the Jewish Telegraphic Agency, Columbia representatives defended Yarhi-Milo in general terms.

“Throughout her time at Columbia and during her service as dean, Dean Yarhi-Milo has worked with and supported students of all backgrounds, including our Palestinian, Arab, and Muslim students,” the statement reads. “The University is grateful for her tireless efforts on behalf of our students and her commitment to a campus free of discrimination and harassment.”

Columbia representatives declined to comment further on the lawsuit but said that “creating a campus environment where every member of our community feels welcome, supported, and safe is ​fundamental to who we are as a university. It is also a responsibility we take seriously.”

A leading figure of the encampment movement that began at Columbia before spreading to schools across the country, Khalil was the first pro-Palestinian student protest leader to be detained by the Trump administration and spent months in an immigrant detention center despite holding a green card. 

In the months since a federal judge ordered his release, Khalil has filed a number of lawsuits, including against pro-Israel groups that he said “conspired” with the government to target him. He has also sued Columbia before, for disclosing student records as part of a congressional investigation.

Khalil’s latest lawsuit against Columbia claims the school violated Title VI protections for him and his fellow plaintiffs based on their ethnic identity, national origin or “affiliation with Palestine.” The lawsuit invokes the same federal civil rights law that Jewish and Israeli students have used in discrimination claims against universities, some of which have resulted in settlements. 

Columbia itself signed a controversial agreement with the Trump administration last year to resolve federal civil rights investigations, paying $221 million and agreeing to a number of concessions in order to free up hundreds of millions in federal funding. During his press conference Monday, Khalil called such settlements “disgraceful.”

The suit notes that, as a student, Khalil called Yarhi-Milo “genocidal” in a message to fellow students. The suit then describes a subsequent internal university investigation into Khalil as “unfounded and retaliatory,” and claims the school “repeatedly launched meritless allegations of antisemitism against Mr. Khalil” prior to his federal detention.

During the press conference, Khalil accused Yahi-Milo of being someone who “weaponizes her identity to shield herself from legitimate concerns and criticism.” Khalil added, “Her priority has never been her students, me and my fellow students here. Her priority has always been Israel.”

The lawsuit’s examples of indifference include a claim that Columbia failed to intervene when a right-wing group, Accuracy in Media, labeled some of the members of Palestine Working Group as “Columbia’s Leading Antisemites” in messages on the side of trucks driven near campus for months after the Oct. 7, 2023, Hamas attacks. The group had targeted pro-Palestinian students in a similar fashion at several campuses.

Joseph Howley, a classics professor at Columbia who is Jewish, spoke at the press conference in support of Khalil, whom he called a friend. “We all see how the university’s anti-Palestinian racism has directly endangered its students,”  said Howley, who wore a Jews for Racial and Economic Justice hat and a “Not In Our Name” shirt. “I won’t be wasting any more time on town halls or listening sessions or imagining anything.”

In a statement to JTA, Accuracy in Media president Adam Guillette said his group “uses publicly available information, and we are steadfastly opposed to doxxing. We pledge to continue delivering accountability to pro-Hamas radicals across the country.” PJC
