Mahmoud Khalil, a green card holder, who was a graduate student at Columbia until December, was detained Saturday by federal immigration agents in New York and flown to an immigration jail in Louisiana.
“We know there are more students at Columbia and other Universities across the Country who have engaged in pro-terrorist, anti-Semitic, anti-American activity,” Trump wrote in a social media post. “We will find, apprehend, and deport these terrorist sympathizers from our country — never to return again.”
But a federal judge in New York City ordered Monday that Khalil not be deported while the court considered a legal challenge brought by his lawyers. A hearing is scheduled for Wednesday.
Khalil is the first person known to be detained for deportation under Trump’s promised crackdown on student protests.
Federal immigration authorities also visited a second international student at Columbia on Friday evening and attempted to take her into custody but were not allowed to enter the apartment, according to a union representing the student.
Khalil, 30, had not been charged with any crime related to his activism, but Trump has argued that protesters forfeited their rights to remain in the country by protests he claimed support Hamas, the Palestinian terrorist group that carried out the massacre of more than 1200 Israeli men, women and children on Oct. 7, 2023. The terrorist group also took more than 200 people hostage.
The U.S. Education Department on Monday warned some 60 colleges, including Harvard and Cornell, that they could lose federal money if they fail to uphold civil rights laws against antisemitism and ensure “uninterrupted access” to campus facilities and education opportunities. The Trump administration is already pulling $400 million from Columbia.
A group of Columbia faculty members expressed concern Monday that Khalil's detention was intended to suppress free speech by students and staff who are not U.S. citizens.
“The attack on Mahmoud Khalil is intended to make them quake in their boots, and to make all of us quake in our boots," said Michael Thaddeus, a Columbia math professor. "Our message to Washington is that we are not silenced, we are not afraid, and we stand together, determined to defeat this ongoing assault on our fundamental rights.”
In their legal complaint, Khalil's attorneys accused the government of retaliating against him for his “constitutionally protected advocacy on behalf of Palestinian human rights.”
Born in Syria to Palestinian parents, Khalil entered the U.S. to attend Columbia in 2022. He subsequently got married to an American citizen, who is now eight months pregnant.
Khalil emerged as one of the most visible activists in large protests at Columbia last year, serving as a mediator on behalf of pro-Palestinian activists and Muslim students. That role put him in direct touch with university leaders and the press — and drew attention from pro-Israel activists, who in recent weeks called on the Trump administration to deport him.
