The Trump administration is preparing to designate Iran’s Revolutionary Guards Corps a “foreign terrorist organization” in an unprecedented move that could have widespread implications for U.S. personnel and policy. U.S. Officials say an announcement could come as early as Monday, April 8, 2019, following a months-long escalation in the administration’s rhetoric against Iran. The move would be the first such designation by any U.S. administration of an entire foreign government entity.  (AP Photo/Ebrahim Noroozi, File)
