WASHINGTON >> The Trump administration is preparing to designate Iran’s Revolutionary Guards Corps as a “foreign terrorist organization” — 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, after a monthslong 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, although portions of the Guard Corps have been targeted before.

Two U.S. officials and a congressional aide are confirming the move. They’re not authorized to discuss the matter publicly and are speaking on condition of anonymity.

The designation comes with sanctions, including freezes on some assets and a ban on Americans doing business with the group.
