Rep. Matt Gaetz (R-Fla.), a close Trump ally who has publicly defended the strike, spent a significant amount of time following Wednesday’s briefings in discussions with House Democrats about fine-tuning the resolution. On Thursday, he announced on the floor that he would support it.

“I support the president, killing Soleimani was the right decision. But engaging in another forever war in the Middle East would be the wrong decision,” Gaetz said, announcing his yes vote.

But the critical forum is the Senate, where Democrats are in the minority and will need the help of at least four Republicans to pass a similar war powers resolution from Sen. Tim Kaine (D-Va.), which could come up for a vote as early as next week. Republican Sens. Mike Lee (Utah) and Rand Paul (Ky.) committed to supporting Kaine’s resolution upon exiting the administration’s briefing Wednesday, after administration officials failed to specify when, if ever, they might seek Congress’s approval for military strike.
