NEW YORK (AP) — Federal immigration authorities arrested a Palestinian activist Saturday who played a prominent role in Columbia University’s protests against Israel, a significant escalation in the Trump administration’s pledge to detain and deport student activists.
Mahmoud Khalil, a graduate student at Columbia until this past December, was inside his university-owned apartment Saturday night when several Immigration and Customs Enforcement agents entered and took him into custody, his attorney, Amy Greer, told The Associated Press.
A spokesperson for the Department of Homeland Security, Tricia McLaughlin, confirmed Khalil’s arrest in a statement Sunday, describing it as being “in support of President Trump’s executive orders prohibiting anti-Semitism.”
Khalil's arrest is the first publicly known deportation effort under Trump's promised crackdown on students who joined protests against the war in Gaza that swept college campuses last spring. The administration has claimed participants forfeited their right to remain in the country by supporting Hamas.
McLaughlin signaled the arrest was directly connected to Khalil's role in the protests, alleging he “led activities aligned to Hamas, a designated terrorist organization.”
In a message shared on X Sunday evening, Secretary of State Marco Rubio said the administration “will be revoking the visas and/or green cards of Hamas supporters in America so they can be deported.”
The Department of Homeland Security can initiate deportation proceedings against green card holders for a broad range of alleged criminal activity, including supporting a terror group.
Khalil, who received his master's degree from Columbia's School of International Affairs last semester, served as a negotiator for students as they bargained with university officials over an end to the tent encampment erected on campus last spring.
The role made him one of the most visible activists in support of the movement, prompting calls from pro-Israel activists in recent weeks for the Trump administration to begin deportation proceedings against him.
Khalil was also among those under investigation by a new Columbia University office that has brought disciplinary charges against dozens of students for their pro-Palestinian activism, according to records shared with the AP.
The investigations come as the Trump administration has followed through on its threat to cut hundreds of millions of dollars in funding to Columbia because of what the government describes as the Ivy League school’s failure to squelch antisemitism on campus.
