H.R. 8707, the No Funds for Iran War Act, prohibits the federal government from spending any money on military force against Iran from the bill's enactment through December 31, 2026, unless Congress formally declares war on Iran or passes a specific new law authorizing such military action. The bill creates exceptions for defensive actions consistent with the War Powers Resolution, such as responding to imminent attacks against the United States or its allies, provided the President complies with required War Powers notification procedures. The legislation applies to all federal funds and affects the executive branch's ability to conduct military operations against Iran. This bill would require explicit congressional approval before offensive military operations could proceed, giving lawmakers direct control over whether the U.S. engages in military conflict with Iran during the specified timeframe.
