Attorneys for Columbia University student Mahmoud Khalil unveiled new footage on Monday illustrating the moments before his March arrest, challenging the government’s claim of him being a flight risk, which was used to justify his warrantless detention.

Khalil, a Syrian-born individual with permanent residency who was instrumental in organizing pro-Palestinian protests on campus a year prior, has been confined in a Louisiana detention facility for two months. He has been contesting both his detention and potential deportation since his arrest—a pivotal case in the current administration’s focus on students protesting the war in Gaza.

Khalil’s attorneys acquired the five-minute surveillance footage via a subpoena, which Columbia University honored. The soundless video, with obscured faces of Immigration and Customs Enforcement agents, is part of five hours of footage that the university provided to Khalil’s defense team.

The video begins in the lobby of Khalil’s New York City apartment building with him speaking to his attorney on the phone and interacting with the four ICE officers while his wife, Dr. Noor Abdalla, walks toward a hallway. Abdalla, according to Khalil’s legal team, went to get Khalil’s green card from their apartment. 

Khalil can also be seen interacting with the ICE agents and handing them his phone twice to speak with his attorney, his legal team said. Khalil appears calm and cooperative, and at one point he appears to laugh with the agents. 

At the end of the video, Abdalla returns to the lobby and gives Khalil his green card, which he turns over to the agents. The video ends after Khalil hands his green card to them. 

The government said in court documents last month that ICE agents allowed Abdalla to get Khalil’s “conditional residence card which was located in their apartment, in lieu of arresting him,” while Khalil and the agents “remained in the foyer.” 

The government said in its court filing that the agents asked Khalil “to cooperate while they attempted to verify his identify, but the respondent stated that he would not cooperate and that he was going to leave the scene.”

“The HSI supervisory agent believed there was a flight risk and arrest was necessary,” the filing said, referring to Homeland Security Investigations.

The Department of Homeland Security and the Justice Department did not immediately respond Monday night to requests for comment about the newly released security video.

NBC News previously reported video of the moment Khalil was arrested, which showed him cooperating and telling officers, “Yes, I’m coming with you.” That video was recorded by Khalil’s wife. 

Khalil’s legal team said the latest video adds strength to their fight.

“The world now knows ICE unconstitutionally arrested Mahmoud in retaliation for his defense of Palestinian rights and lives,” Ramzi Kassem — a co-director of Creating Law Enforcement Accountability & Responsibility (CLEAR), a legal aid group at City University of New York’s law school — said Monday. “After the government finally admitted that agents did not even have an administrative warrant for Mahmoud’s arrest, this video is the nail in the coffin of ICE’s lies: it shows, plain as day, that Mahmoud was calm and collected and that he never tried to run.”

Khalil has not been accused of criminal conduct, but the Trump administration has argued he should be expelled from the country for his beliefs.

The administration has maintained that it has the authority to deport Khalil because he “led activities aligned to Hamas, a designated terrorist organization.”

NBC News reviewed more than 100 pages of documents the federal government submitted in its effort to deport Khalil, which showed that the government appeared to rely on unverified tabloid articles about him.

Last month, an immigration judge in Louisiana affirmed the federal government’s argument that Khalil’s beliefs threaten national security and justify his deportation. 

Days later, U.S. District Judge Michael Farbiarz of New Jersey ruled that Khalil could continue his fight for freedom in federal court.

His legal team has said it will “continue working tirelessly until Mahmoud is free.”
