Senior current and former officials familiar with the matter tell CNN the White House is considering designating Iran’s powerful Islamic Revolutionary Guard Corps as a foreign terrorist organization, a debate that has senior Cabinet officials squaring off on both sides.

The designation decision, formally under the State Department’s purview, is taking on heightened importance as part of the White House’s increasingly aggressive strategy towards Iran. Officials have been debating it for several months and have yet to reach a consensus.

While some warn a designation could pose risks to US personnel and installations overseas, it would allow the White House to freeze IRGC assets, impose travel bans and levy criminal penalties on top of pre-existing economic sanctions imposed by President Donald Trump.
