Defense Secretary Pete Hegseth on Wednesday castigated members of Congress in both parties for questioning the war in Iran, during a contentious Capitol Hill hearing dominated by a conflict that the Pentagon said had cost $25 billion and 14 American lives so far.
Appearing at what had been scheduled as a routine hearing to review the Defense Department’s nearly $1.45 trillion budget request for the coming year, Mr. Hegseth spent much of his time lashing out at lawmakers whose approval would be needed to provide that funding.
“The biggest challenge, the biggest adversary we face at this point are the reckless, feckless and defeatist words of congressional Democrats and some Republicans,” the defense secretary declared in his prepared remarks to the House Armed Services Committee, before members had asked a single question.
The statement set a hostile tenor for the secretary’s first public testimony on Capitol Hill since the war began, coming after Republicans have for weeks refrained from exercising any public oversight of an operation undertaken without congressional authorization, and which polls indicate is unpopular.
It unfolded just before a 60-day milestone in the conflict that some in the G.O.P. have said could become a pivot point for their so far unconditional backing for President Trump’s conduct of the war, beyond which they may begin demanding more answers about objectives and a plan for extricating American troops.
“Here we are in a full-scale Mideast war, and we’ve seen the costs of that,” Representative Adam Smith of Washington, the senior Democrat on the panel, said, noting military and civilian casualties and asserting that “over a dozen countries now have been dragged into this war in one way or another.”
“Where is this going?” Mr. Smith asked.
Mr. Hegseth and Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, provided few answers about an endgame, though their appearance did yield some new information about the costs and results of the military campaign.
The Pentagon comptroller, Jay Hurst, said the war had so far cost $25 billion, mostly because of the tens of thousands of bombs and missiles used, providing the first such official estimate since Mr. Trump began the operation. He did not elaborate on the figure, which was strikingly smaller than the $200 billion the Pentagon had initially requested for the conflict and suggested a major slowdown in expenditures since the start of the war, when officials estimated it had cost more than $11 billion in its first six days.
General Caine put the number of U.S. service members that had died during the war with Iran at 14, slightly above the Pentagon’s own tally of war casualties, which reflects 13 deaths.
After two months of war, General Caine testified, the Iranians “are weaker and less capable than they have been in decades.”
Still asked for a timetable or projected cost for finishing a mission that Mr. Trump initially said would be completed in “four to five weeks,” Mr. Hegseth demurred.
“As you know and as the president has stated, you would never tell your adversary, especially once you’ve decimated their military and you control their strait,” that information, he told Representative Chrissy Houlahan, Democrat of Pennsylvania.
Democrats sharply questioned the objectives for the mission and what had been gained from it. In one particularly heated exchange, Representative John Garamendi, Democrat of California, offered a tally of U.S. losses so far, and asked what the United States had achieved, noting that Iran had retained significant military capabilities and closed the Strait of Hormuz, the strategic waterway for oil shipping.
“You have been lying to the American people since Day 1” of the war, Mr. Garamendi told Mr. Hegseth, accusing him of “incompetence.”
Mr. Hegseth responded by suggesting that the congressman was rooting for the enemy.
“I know the American people support that mission, despite your loose talk,” said Mr. Hegseth, who just a year ago put the flight sequencing of American fighter jets in a group chat on a commercial messaging app. Later, he asked Mr. Garamendi: “Who you cheering for here? Who you pulling for?”
In the hallway outside, protesters had gathered to register their opposition to the war, shouting “war criminal” and “arrest Hegseth” as he arrived to testify.
