Motion to reconsider laid on the table Agreed to without objection.

Iran would be officially named the world's biggest state sponsor of terrorism by the House.

This bill would have the House officially say that Iran is the world's biggest state sponsor of terrorism. It points out Iran's ongoing support for groups like Hezbollah and Hamas. The bill also notes Iran's role in attacks that have killed American citizens and servicemembers, including the January 2024 attack in Jordan that killed three U.S. servicemembers.

What Would Change

Today, the U.S. government already sees Iran as a state sponsor of terrorism. If this bill passes, the House of Representatives would formally declare it to be the official policy of the United States that Iran remains the largest state sponsor of terrorism. This declaration would highlight Iran's ongoing activities, including support for groups like Hezbollah and Hamas, and its role in attacks that have killed hundreds of American citizens and at least 603 U.S. servicemembers. It would also point out the January 2024 attack in Jordan that killed three U.S. servicemembers.
