The House and Senate Armed Services committees received a classified briefing on Iran on Wednesday -- with lawmakers on both sides of the aisle expressing their frustrations over the quality of information they're receiving from senior Pentagon officials.

"We want to know more about what's going on, what the options are and why they're being considered. And we're just not getting enough answers on those questions," Alabama Republican Rep. Mike Rogers, the chairman of the House Armed Services Committee, told reporters after the briefing.

Rogers has indicated that while he is supportive of the operations in Iran, he believes the Trump administration must "be more forthcoming about what's going on, because we're an essential partner in this process."

"This is not just about Epic Fury," Rogers said. "This is a consistent pattern of tagging the base and saying, 'We came over and briefed you,' but they're not telling us things, substantive things."

South Carolina Republican Rep. Nancy Mace told reporters that her concerns about ground troops potentially being deployed in Iran were only emboldened by what she learned in the briefing.

"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," Mace wrote in a post on X. "The longer this war continues, the faster it will lose the support of Congress and the American people."

Washington Rep. Adam Smith, the ranking Democrat on the House Armed Services Committee, acknowledged that while there were some "new details" provided in the briefing regarding munition stockpiles, he questioned the administration's objectives in the operation.

"The objective seems to be basically to fundamentally break Iran so that they no longer have a nuclear program, they no longer have a ballistic missile program, and they no longer support terrorist proxies in the region," Smith said after the briefing. "But we don't have a way from here to there. What is the military plan for getting Iran to the point where they acquiesce on all three of those? We still have not seen the details of what we think we're going to be able to achieve to force them to make those decisions."

Smith said there was discussion about troops on the ground but added that "there were no specific answers" provided by the administration.

The U.S. is on pace to "completely eliminate" Iran's military manufacturing capacity, the head of U.S. Central Command, Adm. Brad Cooper, said in a video released Wednesday.

"Today, we have damaged or destroyed over two-thirds of Iran's missile, drone, and naval production facilities and shipyards, and we're not done yet," Cooper said in the video posted on social media. "We are on a path to completely eliminate Iran's wider military manufacturing apparatus, which is why my operational assessment continues to be Iran's combat capability is declining as U.S. combat capability continues to increase."

Cooper said that just hours ago, the U.S. hit its 10,000th Iranian target in the campaign.

"We're in the fourth week of the campaign and remain on plan or ahead of plan in achieving very clear military objectives for eliminating Iran's ability to project power in meaningful ways outside its borders," Cooper said.

The U.S. has destroyed 92% of the Iranian Navy's largest vessels in Operation Epic Fury, according to Cooper.

"My operational assessment is that they have now lost the ability to meaningfully project naval power and influence around the region and around the world," he said.

Gulf countries issued another condemnation of Iran for its strikes across the region, demanding that "Iran immediately and without condition cease any aggression or threat against neighboring states, including the use of proxies," in a joint statement Wednesday.

The signatories -- Qatar, Kuwait, the United Arab Emirates, Bahrain, Saudi Arabia and Jordan -- also warned that they maintain their right to self defense.

The states "also condemn the acts and activities that undermine the security and stability of regional states, planned by sleeper cells loyal to Iran and related terrorist organizations affiliated with Hezbollah," the countries wrote in the statement.
