On March 8, 2025, Immigration and Customs Enforcement (ICE) agents entered the university apartment of Mahmoud Khalil, a Palestinian student activist at Columbia University, claiming they were acting on a State Department order to revoke his green card, according to his attorney.
Later that day, the Department of Homeland Security justified Mr. Khalil’s arrest by stating that his activities were aligned with Hamas, a designated terrorist organization.
In a social media post, ICE and the Department of State explained that Mr. Khalil was arrested in support of President Trump’s executive orders prohibiting anti-Semitism and to protect U.S. national security.
This incident occurred after the Trump administration moved to cancel $400 million in grants and contracts to Columbia University due to alleged inaction in addressing persistent harassment of Jewish students.
Mr. Khalil, a graduate student at Columbia, was involved in pro-Palestine protests and was detained despite being a legal permanent resident with a green card, not a student visa.
His lawyer, Amy E. Greer, filed a petition challenging the validity of his arrest and detention. As of March 10, 2025, Mr. Khalil’s location was uncertain, with reports suggesting he may be in an immigration detention facility in Jena, Louisiana.
Secretary of State Marco Rubio announced plans to revoke visas and green cards of Hamas supporters in America for deportation.
A pro-Palestine group claimed Mr. Khalil was abducted without a warrant or official charges, despite having a green card and being a lawful permanent resident.
President Trump confirmed Mr. Khalil’s arrest in a social media post and indicated more arrests would follow.
The Trump administration had previously announced plans to revoke visas of Hamas sympathizers, specifically targeting Columbia University students.
Critics condemned Trump’s proposal to control Gaza and transform it into a resort, calling it a plan for ethnic cleansing.
On March 5, 2025, NYPD officers were deployed at Columbia University’s Barnard College during protests over pro-Palestine activism.
Columbia University faced accusations of anti-Semitism and online campaigns against Mr. Khalil by pro-Israel groups.
The university acknowledged ICE’s presence on campus but did not comment on Mr. Khalil’s detention.
