The two measures came to the floor less than a month after Trump authorized an airstrike in Iraq that killed Iranian Gen. Qassem Soleimani, a move largely lauded by Republicans but criticized by Democrats who questioned the constitutionality of the action.

The measure passed in a 228-175 vote, with GOP proponents of the measure arguing Congress needs to reclaim its constitutional powers.

“Under Article II of the Constitution, the President ALWAYS has the legal authority and moral obligation to respond to attacks and imminent threats. Khanna’s bill worked to make that clear by referencing the War Powers Resolution,” Davidson told The Hill.

Hollingsworth focused on the funding aspect.

“Funding our military operations is an essential Constitutional duty reserved only for Congress," he said in a statement. "Our Commander in Chief should be able to take isolated and decisive action to keep Americans and service members safe, as President Trump has, but only Congress can declare and fund a war."

A spokeswoman for Massie added that the Kentucky Republican “supports President Trump, and his vote today was not about the president.”

“Our Founding Fathers believed that Congress—not the President—should possess this power," the spokeswoman stated. "Congressman Massie opposes any military action against Iran without a congressional declaration of war.”

The lawmakers' offices did not immediately respond to requests for comment.

The House passed a second Iran-related measure, one that would repeal the 2002 authorization for the use of military force (AUMF).

GOP lawmakers who voted in favor of the measure argued the AUMF is outdated and needs to be overhauled.

"It’s past time to start practicing some AUMF hygiene by taking outdated authorizations off the books," Gallagher said in a statement. "The 2002 AUMF is no longer relevant and its repeal should have no material impact on ongoing operations in the Middle East."

“But let me clear: the conversation shouldn’t end today. We in Congress should continue to debate other existing AUMFs and the War Powers Resolution more broadly in order to reclaim this institution’s most important constitutional authority,” he added.

Gaetz, a staunch Trump ally, argued the U.S. needs to take steps to end its involvement in “forever wars.”

“I come to vote my heart. Instead of sending our soldiers to blood-stained sands of the Middle East, let's care for veterans here at home,” he said on the floor. “Instead of ill-fated adventurism, let's put America first. The best time to vote against the Iraq War was 2002. The second best is today."

A number of Republicans took issue with Democrats using an unrelated bill to pass the measures, preventing the GOP from having the opportunity to attempt to alter the bill at the eleventh hour on the floor.

“I was not in Congress when the current AUMFs were passed. I have supported past measures repealing the 2001 and 2002 AUMFs, which also gave Congress time to replace them,” Cooper said in a statement. “This is the most complex region in the world and repealing a law without a replacement strategy is no way to keep our troops or America safe.”
