NEW YORK--U.S. immigration agents arrested a Palestinian graduate student who has played a prominent role in pro-Palestinian protests at New York's Columbia University, the student workers' labor union said on Sunday.
The student, Mahmoud Khalil at the university's School of International and Public Affairs, was arrested by U.S. Department of Homeland Security agents at his university residence on Saturday, the Student Workers of Columbia union said in a statement. His wife is an American citizen, eight months pregnant, according to news reports, and he holds a U.S. permanent residency green card, the union said.
Khalil's detention appears to be one of the first efforts by U.S. President Donald Trump, a Republican who returned to the White House in January, to fulfill his promise to seek the deportation of some foreign students involved in the pro-Palestinian protest movement, which he has called antisemitic. The Hamas attack on Israel in October 2023 and subsequent U.S.-supported Israeli assault on Gaza have led to months of pro-Palestinian and anti-Israel protests that have roiled U.S. college campuses.
Khalil calls it an anti-war movement that includes Jewish students and groups, and he was one of the lead negotiators with school administrators on behalf of pro-Palestinian student protesters, some of whom set up tent encampments on Columbia lawns last year and seized control of an academic building for several hours before Columbia called in police to arrest them. Khalil was not in the group that occupied the building, but was a mediator between Columbia vice provosts and the protesters.
In an interview with Reuters a few hours before his arrest on Saturday about Trump's criticism of student protesters, Khalil said he was concerned that he was being targeted by the government for speaking to the media.
Khalil grew up in a Palestinian refugee camp in his native Syria and has worked for the British embassy in Beirut, according to an online biography. He was being held on Sunday at a U.S. Immigration and Customs Enforcement detention center in Elizabeth, New Jersey, according to the ICE online detainee locator. His lawyer, Amy Greer, did not respond to requests for comment. Khalil's wife declined to comment through one of Khalil's fellow students.
A spokesperson for Columbia said the school was barred by law from sharing information about individual students, but said in a statement the school was "committed to the legal rights of our students."
Spokespeople for Trump and the Department of Homeland Security did not respond to questions.Secretary of State Marco Rubio shared a news report of Khalil's arrest on social media, adding the comment: "We will be revoking the visas and/or green cards of Hamas supporters in America so they can be deported." He did not elaborate and spokespeople for Rubio did not respond to questions.
Trump has singled out Columbia for its handling of student protesters and has quickly increased pressure on the school: Khalil's arrest came a day after the Trump administration said it had cancelled government contracts and grants awarded to Columbia University worth about $400 million. The government said the cuts and the student deportation efforts, which are likely to face legal challenges, are because of antisemitic harassment at and near Columbia's Manhattan campus.
"What more can Columbia do to appease Congress or the government now?" Khalil told Reuters hours before his arrest, noting that Columbia had twice called in police to arrest protesters and had disciplined many pro-Palestinian students and staff, suspending some. "They basically silenced anyone supporting Palestine on campus and this was not enough. Clearly Trump is using the protesters as a scapegoat for his wider agenda fighting and attacking higher education and the Ivy League education system."
