“For the first time in history, Congress has passed a war powers resolution directing the president to end hostilities.”

The House passed the Iran measure 215–208 on June 3, 2026, and the Senate adopted it 50–48 on June 24. Calling it the first war powers resolution Congress has ever passed overstates the history: both chambers passed a Yemen war powers resolution in 2019 and an Iran war powers resolution in 2020, and President Trump vetoed each one. The accurate first is narrower — this is the first time both chambers have used a concurrent resolution under Section 5(c) of the War Powers Resolution to direct removal of forces from active hostilities, a form that does not require the president’s signature and cannot be vetoed. Whether it binds the president as a matter of law remains contested.
