Reps. Ro Khanna (D-CA) and Thomas Massie (R-KY) plan to introduce and attempt to force a vote on a war powers resolution blocking military action against Iran without congressional authorization, as the Trump administration appears to be moving closer to military action against the Islamic Republic.

“[Massie] & I have a War Powers Resolution to debate & vote on war before putting U.S. troops in harm’s way. I will make a motion to discharge to force a vote on it next week,” Khanna wrote on X on Wednesday.

He framed the legislation as an attempt to block a “disastrous war” with Iran that “would be catastrophic.”

“Like the votes before the Iraq war, this could be one of the most consequential votes in the history of Congress,” Khanna said. “Are we going to stop another endless dumb foreign war? Or will the neoconservatives mislead us once again?”

He said that lawmakers must go on the record about where they stand on a potential conflict.

“A war with Iran would be catastrophic. Iran is a complex society of 90 million people with significant air defenses and military capabilities. We also have 30-40k U.S. troops in the region who could be at risk of retaliation. Congress must do its job and stop this march to war,” Khanna said.

Once introduced, there will be a waiting period of 15 House session days before the lawmakers can force a vote on the resolution.

Similar legislation is pending in the Senate, introduced by Sens. Tim Kaine (D-VA) and Rand Paul (R-KY), but the two have not yet called it up for a vote. Kaine said last week he was waiting to see the trajectory of the negotiations between the U.S. and Iran.

Several similar resolutions were introduced by House lawmakers after the Operation Midnight Hammer strikes last June, but never came to votes.
