King Joins Colleagues Demanding Answers from Hegseth on Human, Economic Cost of Iran War

September 18, 2026
WASHINGTON D.C. — U.S. Senator Angus King (I-ME), a senior member of the Senate Armed Services Committee, is calling on the Pentagon to provide basic information on the cost to American taxpayers of the Iran War. In a letter to Department of Defense (DoD) Secretary Pete Hegseth from King and several of his colleagues, the senators demand a full accounting of the costs of the ongoing war with Iran and criticized the DoD for withholding basic budget information from Congress and the American public even as U.S. casualties and costs continue to increase.
In their letter, the senators highlight the contrast between the current Pentagon’s transparency record with past wartime practice, noting that Secretary Hegseth has briefed Congress only seven times in six months and held just eight Pentagon press briefings or interviews since the war began, compared to more than 70 press briefings in the first month of the Iraq War alone. The senators also criticized the administration’s public supplemental funding request as a seven-page document offering only vague line items, in contrast to the detailed, hundred-page supplemental requests provided to Congress during the Iraq and Afghanistan wars.
The senators wrote, “We write regarding the Department of Defense’s failure to provide the American people with basic information about the war with Iran and its cost to taxpayers, even as the human costs of this war rise. More than six months into a war that the President said would last six weeks, 18 American servicemembers have been killed, 824 have been wounded, and more than 50,000 troops are currently deployed in the Middle East…Meanwhile, at home, American taxpayers have already paid an extra $100 billion out of their pockets for higher gas and diesel prices alone and at least another $60 billion in higher costs for things like groceries, mortgages, and plane tickets as a result of the war. Now you are asking that they pay again to fund a war of choice that Congress never authorized and the President launched with no strategic plan.”
“Based on the little information provided, the Department says it has already spent $42 billion on this war, though unofficial estimates put that figure much higher,” the Senators continued. “In June, you formally asked the American taxpayers to foot the bill for a $67 billion Iran war supplemental request. This is on top of the Pentagon’s $1.5 trillion fiscal year 2027 budget request. And all of these pending requests come while the Department still has $34 billion in unspent funding from the One Big Beautiful Bill Act. In the last week, the Congressional Budget Office and the Department of Defense Office of the Inspector General have issued their own reports with inconsistent numbers.”
The senators concluded, “The American people elected us to be responsible stewards of their tax dollars. The information we are requesting is the bare minimum required for us to carry out that responsibility.”
In addition to Senator King, the letter is signed by Senators Elissa Slotkin (D-MI), Angela Alsobrooks (D-MD), Tammy Baldwin (D-WI), Michael Bennet (D-CO), Richard Blumenthal (D-CT), Lisa Blunt Rochester (D-DE), Cory Booker (D-NJ), Maria Cantwell (D-WA), Chris Coons (D-DE), Catherine Cortez Masto (D-NV), Tammy Duckworth (D-IL), Richard Durbin (D-IL), Ruben Gallego (D-AZ), Kirsten Gillibrand (D-NY), Maggie Hassan (D-NH), Martin Heinrich (D-NM), John Hickenlooper (D-CO), Mazie Hirono (D-HI), Tim Kaine (D-VA), Mark Kelly (D-AZ), Andy Kim (D-NJ), Amy Klobuchar (D-MN), Ben Ray Luján (D-NM), Ed Markey (D-MA), Jeff Merkley (D-OR), Chris Murphy (D-CT), Patty Murray (D-WA), Jon Ossoff (D-GA), Alex Padilla (D-CA), Gary Peters (D-MI), Jack Reed (D-RI), Jacky Rosen (D-NV), Bernie Sanders (I-VT), Brian Schatz (D-HI), Adam Schiff (D-CA), Democratic Leader Chuck Schumer (D-NY), Jeanne Shaheen (D-NH), Tina Smith (D-MN), Chris Van Hollen (D-MD), Mark Warner (D-VA), Raphael G. Warnock (D-GA), Elizabeth Warren (D-MA), Peter Welch (D-VT), Sheldon Whitehouse (D-RI), and Ron Wyden (D-OR).
As a member of the Senate Armed Services Committee and the Senate Select Committee on Intelligence, Senator King is recognized as an authoritative voice on national security and foreign policy issues. Immediately following the American airstrikes in Iran earlier this year, he released a statement asking for answers and consultation with Congress before proceeding with further military action in the Middle East. He has also pressed several Pentagon nominees on the total cost of the ongoing conflict in Iran, expressing frustration that neither Congress nor the American people have received a clear accounting of the financial burden of military operations. Senator King has consistently supported War Powers resolutions, asserting Congress’s constitutional authority over military conflicts, specifically demanding that the President either obtain congressional authorization for hostilities or remove U.S. Armed Forces from the conflict. The full text of the letter is available here and below.

Dear Secretary Hegseth:
We write regarding the Department of Defense’s failure to provide the American people with basic information about the war with Iran and its cost to taxpayers, even as the human costs of this war rise. More than six months into a war that the President said would last six weeks, 18 American servicemembers have been killed, 824 have been wounded, and more than 50,000 troops are currently deployed in the Middle East. Our troops have had their deployments extended repeatedly, as with the USS Lincoln and now the 82nd Airborne. Our offices have all received outreach from military families concerned about the safety and well-being of their loved ones serving and sacrificing in this war.
Meanwhile, at home, American taxpayers have already paid an extra $100 billion out of their pockets for higher gas and diesel prices alone and at least another $60 billion in higher costs for things like groceries, mortgages, and plane tickets as a result of the war. Now you are asking that they pay again to fund a war of choice that Congress never authorized and the President launched with no strategic plan.
Based on the little information provided, the Department says it has already spent $42 billion on this war, though unofficial estimates put that figure much higher. In June, you formally asked the American taxpayers to foot the bill for a $67 billion Iran war supplemental request. This is on top of the Pentagon’s $1.5 trillion fiscal year 2027 budget request. And all of these pending requests come while the Department still has $34 billion in unspent funding from the One Big Beautiful Bill Act. In the last week, the Congressional Budget Office and the Department of Defense Office of the Inspector General have issued their own reports with inconsistent numbers.
Despite your stated needs, you have repeatedly refused to share basic information that previous Administrations, Republican and Democratic, provided to the American public and Congress during times of war. Donald Rumsfeld, as Secretary of Defense during the Iraq War, briefed Congress more than 20 times in the first six months of that war. In his briefings, he publicly provided granular detail about the war, including objectives; precise figures on damaged aircraft; quality of life for our troops—down to the number of days it took to deliver mail; and detailed breakdowns for transportation, operational support, and munitions replenishment costs in the supplemental request. In stark contrast, you have briefed Congress just seven times in that same period and, in those appearances, refused to answer basic questions about the objectives and cost of this war. Your Department has held only eight Pentagon press briefings or interviews since the start of the Iran War, compared to more than 70 in the first month of the Iraq War alone.
This lack of basic information extends to the Pentagon’s spending. During the wars in Iraq and Afghanistan, Congress regularly received public supplemental requests that were more than a hundred pages long, with detailed explanations for how funding would be used, down to the number of barrels of fuel. In contrast, your public $67 billion Iran war supplemental request was a thin, seven-page document with only vague descriptions, such as “$1.2 billion for Administration priorities.”
Despite asking for tens of billions of additional taxpayer dollars, you have so far failed to provide basic information on how this money has and will be spent. Congress must have access to this information to carry out our oversight responsibilities. It is the bare minimum that any American would expect in balancing their own household budget.
You shared this belief before entering government. In 2012, you criticized the Department’s ability to “shift literally hundreds of millions of dollars from program to program with little accountability.” You added, “[r]eforming the culture at the Pentagon to bring greater spending accountability will be difficult, but it’s long overdue.” And just last year, you said that “the American taxpayers deserve” to know where their money goes, “how it's spent and make sure it's spent wisely.” We agree.
Given this, we request the following information to inform the Senate’s decision-making by September 30, 2026.
The American people elected us to be responsible stewards of their tax dollars. The information we are requesting is the bare minimum required for us to carry out that responsibility. We look forward to receiving your response.
Sincerely,
###
