Kansas Senator Roger Marshall voted no on all 15 Senate roll calls on measures to end U.S. military action against Iran that Congress never authorized, from a June 27, 2025 vote after the first strikes to a September 24, 2026 vote that failed 49 to 50. Four of those measures failed by a single vote, so his vote alone would have changed each result. The war that began on February 28, 2026 has killed 21 U.S. service members and injured 865.
Marshall also cast one of the 50 votes that confirmed Pete Hegseth as secretary of defense, who then ran the war. He called the first strike "bold, necessary, and long-overdue", and on June 28, 2026 he said "The major war is over and think of this as almost just a mop-up operation"; fighting restarted in July. In Kansas, the war sent fertilizer and diesel prices up for farmers at planting and harvest.
Roger Marshall's Votes and Statements on the Iran War
- Marshall Voted 14 Times in 2026 Against Ending the War With Iran, Four Times When His Vote Would Have Changed the Result. From March 4 to September 24, 2026, Roger Marshall voted no 14 times on Senate measures directing the President to remove forces from hostilities with Iran that Congress had not authorized: on March 4, March 18, March 24, April 15, April 22, April 30, May 13, May 19, June 16, June 23, June 24, July 23, July 30 and September 24. The May 13 measure failed 49 to 50, the July 30 measure lost 49 to 50, the September 24 resolution was rejected 49 to 50 and the June 16 measure failed 47 to 48, so a yes vote from Marshall would have advanced each one. On June 24 the Senate voted 47 to 50 against taking up S.J.Res. 185, the one Iran resolution it had discharged from committee. Most of the war's 865 wounded were hurt after July 7, when fighting restarted, and about 50,000 troops remain in the region; Hegseth has estimated they will remain until at least early 2027, the Center for American Progress reported.
- Marshall Voted Against Limiting Military Action Against Iran After the June 2025 Strikes. On June 27, 2025, six days after U.S. bombers struck three Iranian nuclear sites without Congressional approval, Marshall voted no on bringing up Senator Tim Kaine's resolution to remove forces from hostilities against Iran that Congress had not authorized. It failed 47 to 53. The Defense Intelligence Agency's early assessment said the strikes likely only set it back by months; eight months later the United States launched a major strike on Iran with Israel.
- Marshall Cast One of the 50 Votes That Confirmed Pete Hegseth, Who Ran the War. On January 24, 2025, Marshall voted to confirm Pete Hegseth as secretary of defense. The vote was 50 to 50 and the Vice President broke the tie, so Hegseth would not have been confirmed without Marshall's vote. Marshall also voted to confirm Stephen Feinberg as deputy secretary of defense and General Dan Caine as chairman of the Joint Chiefs of Staff. On the war's first day, a military investigation preliminarily found, the United States was responsible for a Tomahawk missile strike on the Shajareh Tayyebeh Primary School in Minab, using outdated data provided by the US Defense Intelligence Agency, and Iranian authorities said the attack killed at least 175 people, including scores of civilians. The Pentagon put the war's cost at $43.6 billion as of this month in September 2026.
- Marshall Voted to Confirm Kash Patel, Who Fired Iran Counterintelligence Staff Days Before the War. On February 20, 2025, Marshall voted to confirm Kash Patel as FBI director; he was confirmed 51 to 49. Days before the war began, Patel fired a dozen agents and staff members from a counterintelligence unit tasked with monitoring threats from Iran, CNN reported, citing two sources, and officials worried that investigations of threats inside the country could be hampered by a mass exodus of national security experts.
- Marshall Voted Against a Plan to Protect Consumers From Iran-War Price Increases in April 2026. On April 22, 2026, Marshall voted no on waiving budget rules for Senator John Hickenlooper's amendment "to establish a deficit-neutral reserve fund relating to ensuring that consumers are protected from price increases associated with tariffs and the Iran war." It failed 47 to 51. By October 16 the national average for gasoline was $4.33 a gallon, or 45% above its prewar level, and Moody's economist Mark Zandi put the war's cost at about $2,000 per household, including $1,100 in higher energy prices, $540 in higher interest rates.
- Marshall Called the Attack on Iran a Bold and Long-Overdue Strike. In a statement dated March 5, 2026, after the first 2026 war powers vote, Marshall said: "Today, I voted against the Democrat War Powers Resolution" and "Our military executed a bold, necessary, and long-overdue strike" against Iran. On June 18, 2026, he told CNN that if Iran did not meet the terms of a new agreement, "if they don’t get it done in 60 days, they may become glass," and that "we could really bomb them back to the dark ages just in two weeks." The war he praised has killed 21 service members as of the Pentagon's October 15, 2026 report, and the United States resumed military strikes against Iran in July 2026, after the June agreement, according to the Center for American Progress.
- Marshall Said the Iran War Was Over in June 2026; Fighting Restarted in July. On June 18, 2026, Marshall told CNN "Americans are done with forever wars" and said "gas prices are plummeting" after a memorandum of understanding with Iran. On June 28, 2026 he said on NBC's Meet the Press: "The major war is over and think of this as almost just a mop-up operation." Fighting in the war restarted in July, then paused in August, and of the 865 service members wounded, the majority since July 7, Task & Purpose reported. The national average for gasoline stood at $4.33 a gallon, or 45% above its prewar level on October 16, 2026.
What the War Roger Marshall Voted to Continue Cost Kansas
- Fertilizer. After the war began, a Kansas farmer told KWCH that "Urea fertilizer was $370 a ton, four days later it was $850 a ton", and a Kansas farmer told KCUR the attack triggered a spike in fertilizer prices last spring, at planting time.
- Farm fuel and diesel. Kansas State University economist Gregg Ibendahl said $90 oil would add more than $1 per gallon to the cost of fuel for farmers and could add $10,000 to total expenses for a typical Kansas grain farm. At the October 2026 harvest, farm diesel prices have exceeded $6 per gallon in Kansas in recent weeks, and Kansas farmers were paying near-record prices for the diesel that powers his combines and tractors, KCUR reported.
- Gasoline. Regular gasoline in Kansas rose from $2.47 a gallon on February 18, 2026 to $3.88 on August 20, up 57.1 percent, according to AAA prices compiled by Visual Capitalist.
