Mahmoud Khalil, the Columbia University anti-Israel ringleader, has posted bond after the Trump administration was temporarily blocked from deporting him amid their continued effort to hold him on “foreign policy” grounds.

Khalil posted his $1 bond on Thursday afternoon. He has not been released.

The move came after U.S. District Judge Michael Farbiarz sided with Khalil on Wednesday, writing: “The government cannot claim an interest in enforcing what appears to be an unconstitutional law.”

Khalil, they said, willfully failed to disclose his employment with the Syrian office in the British Embassy in Beirut when he applied for permanent U.S. residency. The agency also accused Khalil of failing to disclose his work with the United Nations Relief and Works Agency for Palestine Refugees and membership in Columbia University Apartheid Divest.

U.S. Secretary of State Marco Rubio has cited a provision in the Immigration and Nationality Act of 1952 to justify Khalil’s removal from the U.S. The provision allows the Secretary of State to deport noncitizens if the secretary determines their presence in the U.S. “would have serious adverse foreign policy consequences.”

Rubio accused Khalil of participating in “antisemitic protests and disruptive activities, which foster a hostile environment for Jewish students in the United States.”

“Condoning antisemitic conduct and disruptive protests in the United States would severely undermine that significant foreign policy objective,” Rubio wrote.

Khalil has Algerian citizenship through his mother, but was born in a Palestinian refugee camp in Syria.
