This bill directs the Secretary of State to designate twelve Iranian-affiliated organizations as foreign terrorist organizations within 90 days of enactment, including groups like the Houthis, Badr Organization, and various militia brigades, as well as any entities controlled by Iran's Islamic Revolutionary Guard Corps. The President must also determine within 60 days whether to impose financial sanctions on six of these organizations, including asset freezes and transaction prohibitions under existing executive authority to combat terrorism financing. The bill affects these designated groups and any individuals or entities that do business with them, potentially disrupting their funding and international operations. The legislation requires the Secretary of State to submit reports to Congress every 180 days on additional organizations that may meet designation criteria, and the President must report within 60 days on whether sanctions were imposed, with an explanation if any organization was not sanctioned. No specific funding is allocated in the bill, as it primarily uses existing legal authorities and reporting mechanisms already available to the executive branch.
