A Cornell University student whose visa was revoked over his participation in pro-Palestinian campus demonstrations has left the United States voluntarily after a judge declined to immediately block the government from taking steps to deport him.

A senior official with the U.S. Department of Homeland Security claimed, without evidence, that the student was a "terrorist sympathizer."

Momodou Taal, 31, said he left the U.S. voluntarily after a judge didn't block the U.S. government from going through the process to deport him.
