Skeptical Democrats confront Hegseth about Iran war for the first time since conflict started

While Republicans focused on the details of military budgeting and voiced support for the operation, Democrats pivoted to the ballooning costs of the war, the huge drawdown of critical U.S. munitions and the bombing of a school that killed children. Some lawmakers also questioned President Donald Trump's dealings with allies and his shifting justification for the conflict.

Hegseth dismissed the criticism as political and rebuked lawmakers who pushed him for answers.

"The biggest challenge, the biggest adversary we face at this point are the reckless, feckless and defeatist words of congressional Democrats and some Republicans," Hegseth said.

Democrats press Hegseth over reasons for war

Wednesday's hearing stretched nearly six hours as Democrats and some Republicans questioned Hegseth over the war and his ouster of several top military leaders.

In one tense exchange, Hegseth told Democratic Rep. Adam Smith that Iran's nuclear facilities were obliterated in a 2025 attack by the U.S., prompting Smith to question the Trump administration's reasoning for starting the Iran war less than a year later.

"We had to start this war, you just said 60 days ago, because the nuclear weapon was an imminent threat," said Smith, the ranking Democrat on the committee. "Now you're saying that it was completely obliterated?"

Hegseth responded by saying that Iran "had not given up their nuclear ambitions" and still had thousands of missiles.

Smith said the war "left us at exactly the same place we were before."

Democrats accused Hegseth of misleading Americans about the reasons for the conflict and said rising gas prices are now threatening the pocketbooks of millions of people in the U.S.

"Secretary Hegseth, you have been lying to the American public about this war from day one and so has the president," said Rep. John Garamendi of California, who called the war "a geopolitical calamity," a "strategic blunder" and a "self-inflicted wound to America."

Hegseth blasted Garamendi's remarks.

"Who are you cheering for here?" he asked the lawmaker. "Your hatred for President Trump blinds you" to the success of the war.

Hegseth defends firings of top military officers

The defense secretary faced intense questions from Rep. Chrissy Houlahan, a Pennsylvania Democrat, about his decision to oust the Army's top uniformed officer, Gen. Randy George, one of several top military officers to be dismissed since Trump's reelection.

Houlahan said George was deeply respected by both members of the military and Congress and asked why Hegseth fired him. Hegseth's response that "new leadership" was needed failed to satisfy Houlahan.

"You have no way of explaining why you fired one of the most decorated and remarkable men," Houlahan began before Hegseth interrupted her. "We needed new leadership," he repeated.

The Pentagon announced this month that Navy Secretary John Phelan was stepping down. Hegseth previously removed Adm. Lisa Franchetti, the Navy's top uniformed officer, and Gen. Jim Slife, the Air Force's No. 2 leader, while Trump fired Gen. Charles "CQ" Brown Jr. as chairman of the Joint Chiefs of Staff.

Republican Rep. Don Bacon of Nebraska said that while Hegseth is empowered to make personnel changes, he shares what he called "bipartisan concern" about the firings.

"We had a huge bipartisan majority here that had confidence in the Army chief of staff and the secretary of the navy," Bacon said. "And I would just point out it may be constitutionally right ... but it doesn't make it right or wise."

Hegseth has said the changes are part of building a "warrior culture" at the Pentagon.

Republican Rep. Nancy Mace of South Carolina defended Hegseth's personnel moves, saying he is "trying to innovate and trying to change the way we do business."

"I'm glad that you're firing people," Mace said. "There are people there that are getting in your way. They need to go."

Democrats ask about war's cost, Republicans back Trump on Iran

During the extended hearing, Hegseth detailed plans to increase pay for service members and upgrade munitions while also announcing that, as of Tuesday, the Pentagon had authorized $400 million in military aid for Ukraine in its fight against Russia.

But the debate and the questions were dominated by the war in Iran.

While a fragile ceasefire is now in place, the U.S. and Israel launched the war Feb. 28 without congressional oversight. House and Senate Democrats have failed to pass multiple war power resolutions that would have required President Donald Trump to halt the conflict until Congress authorizes further action.

Republicans say they back Trump's wartime leadership, for now, citing Iran's nuclear program, the potential for talks to resume and the high stakes of withdrawal. Still, GOP lawmakers are eager for the conflict to end, and some are eyeing future votes that could become an important test for the president if the war drags on.

Democrats questioned Hegseth over the war's economic impact and rising gasoline costs, noting Trump's promise to lower consumer costs. Hegseth responded by citing the threat posed by Iran.

"What is the cost of Iran having a nuclear weapon that they wield?" he said.

Republicans expressed support for Trump's decision to strike Iran, including Mace, who in late March had expressed concerns about the justification for the war. "The longer this war continues, the faster it will lose the support of Congress and the American people," she wrote in a social media post.

On Wednesday, Mace noted her past concerns but said she is "impressed with where we are today." She told Hegseth: "Everything I have seen, you have surpassed all of my expectations."

Iran's closing of the Strait of Hormuz, a vital shipping corridor for the world's oil, has sent fuel prices skyrocketing and posed problems for Republicans ahead of the midterm elections. The U.S. has imposed a naval blockade of Iranian shipping and three American aircraft carriers are in the Middle East for the first time in more than 20 years.

The countries appear locked in a stalemate. Trump told Axios on Wednesday that he is rejecting Iran's proposal to reopen the Strait of Hormuz in exchange for lifting the U.S. blockade.
