Five CSU, four CU international students face visa revocations. Rubio defends revocations, claiming national security concerns.

Ten international students have had their visas revoked by the U.S. Department of Homeland Security across Colorado universities. The University of Colorado released a statement confirming that F-1 visas issued to four international students on its Boulder and Colorado Springs campuses were revoked.

It might be more than 300 at this point. We do it every day. Every time I find one of these lunatics, I take away their visa,” Secretary of State Marco Rubio said at a March 27 news conference.
