This bill blocks the U.S. government from spending money on using military force in or against Iran unless Congress clearly approves it first by declaring war or passing a new, specific law. It also states that older authorizations, like those used after 9/11 or for the Iraq War, cannot be used to justify action against Iran now . The bill keeps in place the usual limits and reporting rules under the War Powers Resolution. It does not itself give any new power to start a war .

There is a narrow exception for urgent self-defense consistent with the War Powers Resolution. Otherwise, the President would need Congress to act before using force against Iran .
