A federal judge has lifted travel restrictions for Mahmoud Khalil, ruling the Palestinian activist and green card holder is free to attend speaking engagements around the U.S. as he fights the Trump administration’s attempts to deport him. The Columbia University graduate was the first pro-Palestinian campus protester to be jailed by the Trump administration over his advocacy work. During a court hearing Thursday, Khalil’s lawyer Alina Das said, “He wants to travel for the very significant First Amendment reasons that are at the bottom of this case.”
