Arrest of Mahmoud Khalil a ‘targeted, retaliatory’ attack on his first amendment rights, say civil rights groups

Free speech organizations and advocates are expressing outrage after a prominent Palestinian activist who helped lead Columbia University’s pro-Palestinian protests last year, was arrested and detained over the weekend.

Mahmoud Khalil, a permanent US resident with a green card, was taken into custody by federal immigration authorities on Saturday night, who reportedly said that they were acting on a state department order to revoke his green card.
