Mahmoud Khalil was completing a master’s degree at Columbia University when, in March 2025, plain-clothed officers from the Department of Homeland Security snatched him from his home in New York and took him to an immigration detention centre; he was then transferred to another facility in Louisiana, more than 1,000 miles away. As a green card holder, Khalil has permanent US residency, but secretary of state Marco Rubio had determined that his continued presence in the country would have “adverse foreign policy consequences for the United States”, and sought his deportation under a legal provision dating back to the McCarthy era. Khalil was released on bail in June 2024 after a federal judge ruled his detention unconstitutional, but the Trump administration is still trying to have him removed.
Khalil – who was born to Palestinian parents in a refugee camp in Syria – had been targeted because of his advocacy on behalf of pro-Palestinian protesters during campus protests over Columbia University’s links to Israel. They were calling for Columbia to cut its ties with Israeli academic institutions and companies profiting from Israel’s onslaught on Gaza; in response, the university called in the NYPD. There was no suggestion that Khalil had done anything unlawful, and no criminal charges were brought against him; the government had simply identified him as an influential pro-Palestinian voice on campus, and for that reason alone they wanted him gone. He spent a total of 104 days in detention, missing the birth of his son.
