A Louisiana judge has given Secretary State Marco Rubio the go ahead to deport Columbia University student and pro-Palestine activist Mahmoud Khalil. Assistant Chief Immigration Judge Jamee Comans said she had no authority to question Rubio after he deemed Khalil’s involvement in last year’s protests—though lawful—antisemitic and a threat to U.

Attorneys for a 21-year-old Columbia University student fighting deportation asked a federal judge late Thursday to order the Trump administration to produce a letter from Sec. of State Marco Rubio that targets two activists for removal under a rarely-invoked federal act.

Khalil, a Columbia graduate student who helped lead protests against the war in Gaza last year, was arrested by immigration authorities on March 8.
