House Republican leaders postponed a critical vote on the Iran war, revealing fractures within the GOP and ensuring geopolitical risk premiums remain a key factor for markets heading into June.

House Republicans on Thursday delayed a vote on a resolution to end the unauthorized war with Iran after at least eight party absences made it clear they lacked the support to defeat it, extending a period of political and market uncertainty. The measure would direct the president to withdraw U.S. forces from the conflict, which began in late February, or gain explicit approval from Congress.
"We had the votes without question and they knew it, and as a result they’re playing a political game," Representative Gregory Meeks, the top Democrat on the House Foreign Affairs Committee who sponsored the bill, said.
The delay follows a previous attempt to pass a similar resolution that failed on a 212-212 tie vote, highlighting the GOP's razor-thin majority. In the Senate, a parallel war powers measure recently advanced on a 50-47 procedural vote, with four Republicans joining Democrats. The conflict has contributed to rising energy costs, with the nationwide average gasoline price climbing to $4.53, a figure cited during recent protests on Capitol Hill.
The procedural maneuver ensures that the debate over the president's war-making authority under the War Powers Resolution of 1973 will continue into June. This maintains the geopolitical risk premium that has affected oil prices and global shipping for over two months and sets up a future vote that could trigger significant market volatility depending on the outcome.
Republican leadership attributed the delay to ensuring absent members could participate. "We’re going to be giving them that opportunity when we come back," Majority Leader Steve Scalise told reporters. However, the move was widely seen as a retreat after it became apparent the resolution was likely to pass, which would have served as a direct rebuke to President Trump.
The growing dissent within Republican ranks stems from the war's duration, now past the 60-day limit that the 1973 law allows for military action without congressional authorization. "We’re past 60 days so it’s got to be brought to us to vote on. We’re following the law," said Representative Brian Fitzpatrick, a Pennsylvania Republican who confirmed he would vote for the resolution. This sentiment signals a widening crack in party unity over the conflict as midterm elections approach.
The stalemate in Washington does little to calm markets. The war has already disrupted shipping in the Strait of Hormuz, a chokepoint for roughly 20% of global oil consumption, according to the U.S. Energy Information Administration. This disruption is a primary driver of the sustained increase in energy costs.
The last time a similar bipartisan challenge to presidential war powers gained this much traction was during the late stages of the Vietnam War, which ultimately led to the original War Powers Resolution. While a successful passage of the resolution would likely face a presidential veto, its advancement through both chambers of Congress would signal escalating political risk and the potential for a constitutional clash, further unsettling investors. The vote is now expected after lawmakers return from their Memorial Day recess in early June.
