Republican Thomas Massie joins with Democrats in effort to require Congress approval before Trump attacks Iran

As Donald Trump publicly threatens to join Israel in attacking Iran, an unlikely coalition of lawmakers has moved to prevent the president from involving US forces in the conflict without Congress’s approval.

On Tuesday, Republican congressman Thomas Massie, whose libertarian-tinged politics have often put him at odds with Trump, joined with several progressive Democrats to introduce in the House of Representatives a war powers resolution that would require a vote by Congress before Trump could attack Iran. Democrat Tim Kaine has introduced companion legislation in the Senate.

“This is not our war. But if it were, Congress must decide such matters according to our Constitution,” Massie wrote on X in announcing the resolution. Democrats Ilhan Omar and Alexandria Ocasio-Cortez replied “signing on” to the tweet, while Massie’s office later announced that several others, including chair of the Congressional Progressive Caucus, Greg Casar, would also sponsor the resolution.
