U.S. Senate Democratic Whip Dick Durbin (D-IL) accused President Donald Trump on Monday of pouring tens of billions of dollars into an open-ended war with Iran while ordinary Americans absorb the rising cost of housing, groceries and gas. In a post on X published at 8:06 a.m. on September 21, 2026, Durbin tied a new Pentagon accounting of the war’s price tag directly to the economic strain he says is being felt in households across the country, arguing the administration has no clear plan to bring the seven-month-old conflict to a close.
Durbin’s post read in full:
“After almost seven months, President Trump’s war with Iran has now cost Americans $43.6 billion. While you pay more every day for your housing, groceries, and gas, President Trump is spending billions on a war he has no idea how to end.”
A Direct Response to Pentagon Numbers
The senator’s post was a direct reaction to Washington Post reporting published three days earlier, which revealed that U.S. Central Command — the combatant command overseeing American military operations in the Middle East — had given Congress a new estimate putting the war’s total cost at $43.6 billion, the highest figure disclosed to date. The report noted the total does not account for damage to American facilities across the Middle East and does not reflect any future costs still facing taxpayers.
According to the document reviewed by the Post, the total includes $28 billion needed to replace munitions but does not account for damage to American facilities throughout the Middle East, along with more than $4.3 billion in equipment lost or damaged during the fighting. The estimate broke out spending by military branch, with Air Force operating expenses topping $6.6 billion, Navy costs near $2.2 billion and Army costs around $1.6 billion.
Separate reporting from CQ Roll Call, drawing on the same Pentagon document, broke the total down differently, describing it as $11.2 billion already obligated for operating expenses — for fuel, combat pay, aircraft, medical care, parts and the like — plus $32.4 billion in unfunded replacement costs for munitions, damaged aircraft and other assets. That outlet also noted the estimate arrived as polls show Americans increasingly oppose the war, partly over its impact on the economy, with the issue set to weigh heavily on the November midterm elections.
Reporting from the Associated Press, added that the figure marks a sharp jump from a Congressional Budget Office estimate released just days earlier putting the war’s cost at $38 billion through August 1. Weapons costs jumped by more than $6 billion in just over a month, from $21.7 billion listed in the CBO report to $28.1 billion in U.S. Central Command’s estimate, underscoring how quickly munitions spending has accelerated.
Seven Months of Escalating Costs
The war, which the United States and Israel launched against Iran on February 28, 2026, has seen its official cost climb steadily throughout the year. Early Pentagon briefings to lawmakers put the price of just the first six days of fighting at more than $11.3 billion, a figure that did not include the cost of the military buildup that preceded the first strikes. By May, as Defense Secretary Pete Hegseth made his first public appearance before Congress since the war began, Pentagon officials pegged the total at $25 billion, then $29 billion less than two weeks later.
Durbin’s Pattern of Criticism
Monday’s post was the latest in a monthslong campaign by Durbin to tie the war’s financial toll to the cost-of-living pressures facing his constituents. In March, speaking on the Senate floor, Durbin argued that Trump had campaigned against new wars but instead delivered one, saying the president had found money for the Iran campaign that he would not direct toward everyday expenses. Durbin said at the time that his constituents were “already paying more on their gas and energy bills” because of the administration’s approach to the Middle East, and predicted the strain would worsen.
Durbin has also pressed Pentagon leadership directly on the war’s rationale and cost. During a May Defense Appropriations Subcommittee hearing, he questioned Hegseth and Joint Chiefs Chairman Gen. Dan Caine about gridlock in the Strait of Hormuz, asking “Can you explain to the American people who are facing these gasoline and diesel oil prices what is going on… as the Strait of Hormuz is at a standstill with 1,500 tankers waiting for permission or a peaceful circumstance to navigate?” General Caine responded that Iran was “choosing to hold the world’s economy hostage.”
Later that month, during a visit to Peoria, Illinois, Durbin again linked the war to consumer prices, telling reporters, “Look at the price of gasoline, and tell me how long the American economy and American families can put up with this situation in Iran.” Local gas prices at the time averaged $4.82 a gallon, up more than a dollar and a half from the year before.
Pentagon’s Defense of the War’s Trajectory
Hegseth has repeatedly defended the administration’s approach when pressed by lawmakers over the war’s mounting costs. Facing bipartisan questioning in May over the then-$29 billion total, Hegseth rejected the notion that U.S. munitions stockpiles were being depleted, telling House and Senate appropriators “I take issue with the characterization that munitions are depleted in a public forum. That’s not true.” He maintained the administration was working to accelerate weapons production even as it continued combat operations.
Asked directly about the war’s economic toll during his first congressional appearance since the conflict began, Hegseth turned the question back on critics, asking lawmakers, “What is the cost of Iran having a nuclear weapon that they wield?” The administration has continued to frame the war’s expense as a necessary investment against a longer-term threat, even as it separately pushes Congress to approve a record $1.5 trillion defense budget for the coming fiscal year.
Economic Fallout Beyond the Pentagon’s Ledger
Outside groups tracking the war’s economic footprint have pointed to broader price increases tied to the conflict. An August analysis found that gasoline prices had climbed from $2.98 a gallon just before the war began to $4.09 a gallon by mid-August, a jump of more than 37 percent, while diesel prices rose by more than 46 percent over the same period. The same analysis noted that the Pentagon has neither provided adequate estimates of the costs of operations to date nor has provided enough clarity and detail around the nature of operations to allow for precise independent accounting.
Separately, Senate Democrats on the Joint Economic Committee estimated in April that the war had already cost American drivers roughly $8.4 billion in higher gas prices alone, based on AAA pump-price data and federal fuel-consumption figures — a distinct calculation from the Pentagon’s own operational cost estimates but one that echoes Durbin’s broader argument that ordinary Americans are shouldering the war’s financial weight far beyond the Pentagon’s ledger.
The Political Stakes Heading Into November
The cost debate is unfolding as both parties look toward the November midterm elections, with the war’s price tag and its effect on consumer prices emerging as a central flashpoint. Reporting has noted that the political price will be tallied in November’s midterm elections, as Republicans confront growing public discontent with the conflict, even as the administration presses forward with its request for a record defense budget and an additional $95 billion package tied in part to war funding.
Durbin, for his part, has been careful to frame his criticism as a rejection of the war’s execution rather than a defense of Tehran, having said previously that “there is no love lost” between him and the Iranian government and that curbing its support for terrorism and nuclear ambitions remains a worthwhile goal. His Monday post did not address that distinction directly, focusing instead on the widening gap between the war’s official cost and the economic pressure he says American families continue to feel with no resolution in sight.
