GOP Lawmakers Clash With Briefers Over Iran War Strategy on Capitol Hill

Rep. Nancy Mace, R-S.C., walked out of a classified House Armed Services Committee briefing on the Iran war and immediately posted on X: "Just walked out of a House Armed Services Briefing on Iran. Let me repeat: I will not support troops on the ground in Iran, even more so after this briefing."

Tensions flared behind closed doors as defense and intelligence officials briefed lawmakers about the war, with Republicans and Democrats expressing frustration about a lack of clarity and information about President Donald Trump's strategy, according to four congressional officials who attended the briefing and a lawmaker who was briefed on it later.

Much of the frustration centered on the prospect of the United States sending ground troops into Iran, including what the troops could be used for and whether the U.S. can adequately protect them once deployed. One of the congressional officials summed up the mood bluntly: "There was no plan, no strategy, no end game shared, and they didn't give any answers. It's unclear if there isn't a plan or if there is a plan and they wouldn't share it with members."

The four congressional officials in the briefing said there was frustration with the defense and intelligence officials over what they view as a lack of a cohesive strategy for the war, specifically where it is heading. They also said tensions flared over conflicting explanations from the administration about the justification for starting the war.

Mace went further in her public statement, writing: "The justifications presented to the American public for the war in Iran were not the same military objectives we were briefed on today in the House Armed Services Committee. This gap is deeply troubling. The longer this war continues, the faster it will lose the support of Congress and the American people."

House Armed Services Committee Chairman Mike Rogers, R-Ala., acknowledged in a text message to NBC News that there has been some frustration with "ALL the briefings that we have been receiving for the last several months," stating that the "criticism has NOTHING to do with Operation Epic Fury" and that he "fully support[s] what the administration is doing in Iran." But Rogers made clear his patience has limits. Lawmakers want more information about what options are being considered as troops move into the CENTCOM combatant command. "And we aren't given any details," Rogers said. "This is one in a series where we feel like the administration needs to be more forthcoming when they send folks over here. That's good that they finally started sending people over here, but they have to tell us meaningful things while they're here."

Rep. Clay Higgins, R-La., said he was personally satisfied with the briefing but described it as the "most contentious" Armed Services Committee briefing he had seen, adding: "I believe members kind of went in there determined to not be satisfied with the administration."

Briefers told the congressional officials that the additional U.S. troops headed to the region are intended to give Trump options. The White House pushed back on the criticism, with spokesperson Anna Kelly noting in a statement that the administration has "briefed Congress throughout Operation Epic Fury and before the military action began," and that the Department of State, Department of War, and Intelligence Community have conducted 20 bipartisan briefings for members of Congress, including two for the House Armed Services Committee.

House Speaker Mike Johnson also defended the administration, saying: "They've given member briefings at the classified level. Every member is privy to whatever information they need and I'm not sure how much more transparent they can be."

Operation Epic Fury was launched on February 28, 2026, as a joint U.S.-Israeli military operation against Iran. Trump, speaking at a Republican fundraiser in Washington Wednesday evening, said he considered an Iran with nuclear potential a "cancer" and defended the war despite its economic effects: "We had no choice." Iran has since rejected a proposed U.S. peace plan, and the administration is simultaneously pursuing diplomacy, sending additional forces to the Middle East, and weighing whether to put American troops on Iranian soil, making Wednesday's briefing room confrontation a preview of the congressional fights ahead.
