U.S. Senator Mazie Hirono (D-HI) accused the Pentagon on Monday of concealing the truth behind President Donald Trump’s ongoing war with Iran, saying the Defense Department’s decision to classify the mission statement for Operation Epic Fury suggests officials have grown weary of justifying a conflict she has repeatedly called illegal. Hirono’s remarks, posted to X on the morning of September 21, 2026, mark the latest salvo from the Hawaii Democrat and senior Senate Armed Services Committee member in a monthslong campaign to force transparency from the Trump administration over the human and financial costs of the war.
“Classified? Sounds to me like they got tired of having to lie to the American people for why they started this illegal war,” Hirono wrote at 9:11 a.m. on September 21, 2026.
Hirono’s post was a direct response to reporting from Task & Purpose published September 15, which revealed that the Pentagon’s Office of the Inspector General classified the full mission statement for Operation Epic Fury in its first comprehensive public accounting of the war’s costs and casualties. The watchdog’s report to Congress stated plainly that “the full [Operation Epic Fury] mission statement is classified,” an admission that came more than six months after the war began.
The Inspector General’s report covered costs incurred between April 1 and June 30, even though the Pentagon had officially launched Operation Epic Fury on February 28. Investigators also folded in casualty and arms-sales data from outside that window, drawing from March and July, a patchwork approach that has become characteristic of the administration’s public accounting of the war.
A Mission Without a Consistent Explanation
The classification of the mission statement adds to a long pattern of shifting and sometimes contradictory public explanations for why the United States went to war with Iran in the first place. At a March press conference, Defense Secretary Pete Hegseth described the goal of Operation Epic Fury as destroying Iranian weapons and infrastructure to prevent Tehran from acquiring nuclear weapons, while Chairman of the Joint Chiefs of Staff Gen. Dan Caine offered a different framing, telling reporters the objective was to “protect and defend ourselves” and to “disrupt, degrade, deny and destroy Iran’s ability to conduct and sustain combat operations.”
U.S. Central Command, in responding to the Inspector General’s request for information, acknowledged that it “continued to refine and adjust” the mission after it had already begun, according to the watchdog report. Even the operation’s name has proven unstable: after casualties climbed and ceasefires collapsed into renewed hostilities, the Pentagon began recording wounded troops under the generic label “overseas operations” by July rather than under Operation Epic Fury.
Administration officials have at times declared the operation over entirely. Secretary of State Marco Rubio told reporters at a White House briefing on May 5 that Operation Epic Fury “was over,” a claim Hirono and other Democrats have disputed given that American forces resumed near-daily airstrikes on July 6 after a ceasefire collapsed. The State Department’s Office of the Legal Adviser had earlier laid out the operation’s stated legal objectives in an April 21 release, describing the goal as destroying Iran’s offensive missiles, missile production capacity, and naval and security infrastructure, and ensuring Iran “will never have nuclear weapons.”
Hirono’s Monthslong Push for Transparency
Monday’s post continues a pattern of public pressure Hirono has applied on the administration since the war’s earliest days. When Trump first announced strikes on Iran, Hirono issued a statement calling the decision “a clear violation of the Constitution, which gives Congress, not the President, the sole power to declare war,” and said she feared Trump was “recklessly putting the lives of our servicemembers and personnel in the region at risk.”
She has since voted repeatedly to advance War Powers Resolutions aimed at ending the conflict, including one led by Senator Tim Kaine (D-VA). After one such vote, Hirono said Senate Republicans were “betraying the American people and empowering Trump’s lawlessness” by declining to assert congressional war powers, adding that “the capacity of U.S. forces is not infinite” as the administration continued diverting resources into the war without articulating a broader strategy.
In a Senate Armed Services Committee hearing, Hirono directly confronted Hegseth over the war’s toll, telling him that 13 service members had been killed and more than 400 wounded at that point, with taxpayers having already absorbed more than $25 billion in costs. She argued the closure of the Strait of Hormuz was “directly contributing to the unaffordable prices that Americans are facing” and said the war was “driving up costs, undermining readiness, and alienating our allies with neither a clear rationale for starting this war, nor an exit strategy.”
Leading Democrats in Demanding a Casualty Accounting
Hirono’s scrutiny of the Pentagon’s data practices escalated further in late July, when she led every Democrat on the Senate Armed Services Committee in a letter to Hegseth, Caine, U.S. Central Command chief Admiral Brad Cooper, and Under Secretary of Defense for Personnel and Readiness Anthony Tata demanding a full and accurate accounting of Operation Epic Fury casualties. The letter, co-signed by Senators Jack Reed, Jeanne Shaheen, Kirsten Gillibrand, Richard Blumenthal, Tim Kaine, Elizabeth Warren, Gary Peters, Tammy Duckworth, Jacky Rosen, Mark Kelly and Elissa Slotkin, stated that “the American people, Congress, service members, and their families are entitled to a full and accurate accounting of the human costs of war.”
That letter came days after reports that the Pentagon had quietly reduced its official death toll for Operation Epic Fury from 18 to 14 and removed dozens of wounded troops from its public Defense Casualty Analysis System database, changes defense officials attributed to “temporary data disruptions” that were being resolved. Hirono and her colleagues pressed the department on whether service members diagnosed with traumatic brain injuries were being properly counted among the wounded, and who had authorized any decisions to withhold information about Iranian attacks on U.S. forces in Jordan.
Hirono has also backed legislative efforts to force clearer accounting. In August, she co-sponsored a bill introduced by Senator Tammy Duckworth targeting the Pentagon’s inconsistent casualty reporting, a measure that came in response to the administration’s position that Operation Epic Fury formally concluded in May and that fighting resumed as a distinct “new phase” of the conflict in July — a distinction critics say has been used to sidestep public accountability.
The Cost the Watchdog Did Reveal
Despite the classified mission statement, the Inspector General’s report did disclose significant new figures on the war’s toll. It found that the first four months of the operation cost $33.4 billion, including $7.4 billion in contingency operations, $22.3 billion in expended munitions and $3.7 billion in equipment losses. The watchdog cautioned that the true cost is “difficult to calculate” because Congress has not appropriated funding specifically for Operation Epic Fury, forcing the military services to reroute funds originally intended for training and maintenance.
The report also detailed extensive damage from Iranian strikes, friendly fire and accidents, including harm to hundreds of buildings and structures at U.S. bases across Kuwait, Bahrain, Qatar, the United Arab Emirates, Saudi Arabia, Iraq, Oman and Jordan. Aircraft losses included as many as 30 Reaper drones, 12 KC-135 refueling tankers, four F-15E fighter jets, four AH-6 helicopters and one F-35A stealth fighter. As of the report, the Pentagon’s own figures showed 18 service members killed and more than 750 wounded in connection with the war.
An Unresolved Fight Over Accountability
Hirono’s Monday post signals that the fight over transparency in Operation Epic Fury is far from settled, even as the war approaches its seventh month. Her suggestion that the classified mission statement reflects an administration eager to avoid explaining its own war aims echoes arguments she and fellow Democrats have made since the conflict’s opening days — that the strikes were launched without clear congressional authorization, a coherent strategy, or consistent public justification.
With the Duckworth-backed casualty accounting bill still pending and the Senate Armed Services Committee’s Democratic caucus continuing to press Hegseth’s Pentagon for answers, Hirono’s latest remarks are likely to keep the classified mission statement, and the broader question of what the United States is actually trying to accomplish in Iran, at the center of ongoing congressional scrutiny.
