DHS Detains Lead Negotiator of Columbia Gaza Solidarity Encampment, Claiming “Activities Aligned to Hamas”

NEW YORK CITY—On Saturday night, Department of Homeland Security (DHS) agents entered a student residential building at Columbia University in uptown New York and detained Mahmoud Khalil, one of the lead negotiators on behalf of pro-Palestine protesters at 2024’s Gaza solidarity encampment. In a sweeping attack on the First Amendment, the Trump administration said this week it would begin revoking visas of “Hamas sympathizers,” specifically citing Columbia University students. The detention followed a two-day targeted online campaign against Khalil by pro-Israel groups and individuals, including Columbia’s high-profile pro-Israel professor, Shai Davidai.
Khalil, an Algerian citizen of Palestinian origin and an American green-card holder, was detained by DHS officials around half past eight as he was entering the Columbia residential building he lives in. He was returning from an iftar, breaking the day-long fast observed by many Muslims during the month of Ramadan.
Khalil’s wife, who is eight months pregnant, was with him at the time. A statement by the pro-Palestine group Writers Against the War on Gaza (WAWOG) stated that he was “abducted and detained without the physical demonstration of a warrant or officially filed charges.”
Khalil was detained at a DHS facility in New Jersey, according to a database for U.S. Immigration and Customs Enforcement. But when his wife went to try and visit him she was informed he was not there. “He is not at the ICE facility in New Jersey. I can confirm he is not there,” Khalil’s attorney Amy Greer told Drop Site. “At this time, we have an idea [where he is] but we cannot confirm that 100%.”
According to WAWOG, the DHS agents told Khalil that the U.S. Department of State had revoked his student visa. The group said this was “despite the fact that he has a green card, not a visa, and is a lawful permanent resident.”
In response to a request for comment from Drop Site, the DHS first stated, “You need to reach out to the White House.”
On Sunday evening, DHS spokesperson Tricia McLaughlin sent a follow-up statement confirming ICE “arrested” Khalil “for activities aligned to Hamas”: “On March 9, 2025, in support of President Trump’s executive orders prohibiting anti-Semitism, and in coordination with the Department of State, U.S. Immigration and Customs Enforcement arrested Mahmoud Khalil, a former Columbia University graduate student,” McLaughlin wrote. “Khalil led activities aligned to Hamas, a designated terrorist organization. ICE and the Department of State are committed to enforcing President Trump’s executive orders and to protecting U.S. national security.”
McLaughlin did not answer questions about where Khalil is being held.
Columbia University directed Drop Site to a statement on their website. The statement, dated March 9, reads, “There have been reports of ICE around campus. Columbia has and will continue to follow the law. Consistent with our longstanding practice and the practice of cities and institutions throughout the country, law enforcement must have a judicial warrant to enter non-public University areas, including University buildings. Columbia is committed to complying with all legal obligations and supporting our student body and campus community.”
Khalil’s wife was unlocking the door to the building when “two plainclothes DHS agents forced their way in behind them.” They initially refused to identify themselves, she reported, but then threatened Khalil’s wife that if she remained with him, she would be detained too.
On Wednesday, Khalil was among the protesters at a sit-in at Milstein Library in Columbia University’s Barnard College, protesting the recent expulsion of three Barnard students over pro-Palestine activism. New York Police Department officers later arrested nine individuals from the same protest—the third round of arrests of pro-Palestine demonstrators on Columbia’s campuses in the past year.
Over the course of Thursday and Friday, several prominent pro-Israel groups and individuals published a series of tweets targeting Khalil, mentioning his presence at the sit-in on Wednesday and his history as a lead negotiator with Columbia in April 2024, and demanded that the Trump administration act strongly against him by revoking his visa and deporting him. They tagged President Donald Trump, Secretary of State Marco Rubio, and US Attorney General Pam Bondi.
Shai Davidai, a professor at Columbia Business School, who was suspended from entering Columbia’s Morningside campus in 2024 following allegations of misconduct against students and staff of the university, tweeted, “Illegally taking over a college in which you are not even enrolled and distributing terrorist propaganda should be a deportable offense, no? Because that’s what Mahmoud Khalil from @ColumbiaSJP did yesterday at @BarnardCollege”.
“Documenting Jew Hatred on Campus at Columbia U”—an account on X with more than 20,000 followers—tweeted, “Secretary Rubio (@SecRubio), please revoke Mahmoud Khalil’s visa!” On March 6, Rubio had tweeted that “those who support designated terrorist organizations, including Hamas, threaten our national security” and that such “violators of U.S law—including international students—face visa denial or revocation, and deportation.”
A pro-Israel student protester at Columbia shared that Khalil was…
