IOWA — Republican Senate candidate Ashley Hinson called for an "immediate end" to the conflict with Iran on Monday, proposing economic relief measures that include suspending the gas tax and pausing diesel exports. The three-term congresswoman outlined a shift in her approach to the ongoing Middle East conflict, marking a departure from her previous legislative record on war powers.

Hinson has served as the U.S. representative for Iowa's 2nd congressional district since 2021. Her new stance comes as the Cook Political Report shifted its Iowa Senate race rating from "lean Republican" to "toss-up" last month. President Donald Trump won Iowa in the last three presidential elections, but Democrats have not won a Senate race in the state since 2008.

The proposal contrasts with Hinson's voting history in the House of Representatives. Rep. Hinson voted against House resolutions directing President Donald Trump to halt the war with Iran six times. She also voted against a seventh resolution concerning U.S. hostilities in Lebanon as part of the conflict in the Middle East. Last month, Hinson objected to President Trump's proposal to import more foreign beef.

Democratic Senate candidate Josh Turek responded to Hinson's announcement on X, showing her prior votes. ""It’s easy to send a tweet but when you had the chance to vote to end this war, you chose not to," Turek stated. He noted that Hinson voted seven times to continue the conflict, including just last week. Glad you’re finally following my lead after waffling on the proposals I put forward last week to address the rising costs of the war in Iran, Turek said."

Hinson did not attend Vice President JD Vance's rally in Council Bluffs, Iowa, last week, citing a scheduling conflict. During his remarks, Vance acknowledged her absence. I want to make a shoutout to an amazing public servant," Vance said."

The legislative context involves recent votes in Congress regarding military action. On Sept. 15, the House passed H.Con.Res. 93 by a vote of 220–204.

Seven Republicans joined all Democrats present in supporting the latest House resolution on the war with Iran. Reps. Zach Nunn and Marianette Miller-Meeks of Iowa voted for the resolution after previously opposing such measures. U.S. Rep. Randy Feenstra voted against H.Con.Res. 93. The resolution directed the president, under the War Powers Resolution, to remove U.S. forces from hostilities with Iran unless Congress authorized military action, while preserving the president’s authority to respond to an imminent attack. H.Con.Res. 93 did not go to the president for his signature because it was a concurrent resolution.

Nunn reposted a call for action from U.S. Sen. Chuck Grassley and said his plan is to "sell American energy to Americans first," pass an Iowa-led biofuels bill, and hold oil companies accountable. Nunn said Iran should be held accountable for killing Americans, supporting terrorism, threatening the Strait of Hormuz, and pursuing nuclear weapons. He stated that Congress owes military members "clear objectives and constitutional oversight" and that he would not support another open-ended war. The Cook Political Report rates the House races of Nunn and Miller-Meeks as "toss-ups."

Miller-Meeks outlined a six-point plan that includes suspending federal and state fuel taxes, temporarily stopping diesel exports, providing direct relief to farmers and truckers, expanding domestic drilling, allowing year-round E-15, and extending the biodiesel tax credit. Her plan calls for ending the open-ended war with Iran.

Industry groups raised concerns about the proposed export ban. The American Fuel and Petrochemical Manufacturers stated that a diesel-export ban could reduce fuel production because refineries produce diesel and gasoline together. The group argued that if refiners cannot export or store excess diesel, they could reduce production, tightening supplies and raising prices.

They warned that an export ban could weaken U.S. energy security, benefit foreign competitors, and invite retaliation. Interior Secretary Doug Burgum said the administration would consider proposals but was not convinced an export ban would lower prices. Agriculture Secretary Brooke Rollins said the president had discussed diesel relief and that an announcement could be coming soon.

Why It Matters

The shift in Hinson's position reflects broader political dynamics in Iowa, where the Senate race has tightened to a toss-up despite historical Republican strength in presidential elections. The debate over war powers and economic relief intersects with voter concerns about fuel costs and agricultural stability, particularly regarding diesel exports and biofuel credits. The involvement of multiple Iowa lawmakers in recent House votes indicates a fragmented Republican response to the conflict and its domestic economic impacts.

The proposed measures, including diesel export bans and tax suspensions, face scrutiny from industry groups warning of potential supply disruptions and higher prices. The administration's consideration of these proposals, alongside continued legislative efforts to define war powers, shows the tension between immediate economic relief and long-term national security strategy. The outcome of these policy debates may influence both the Senate race and the broader congressional approach to the conflict.

Timeline

On June 30, 2026, the Senate war-powers resolution passed the Senate 50–48. In June, Chuck Grassley voted against a similar Senate war-powers resolution.

Also on August 21, the Cook Political Report shifted its Iowa Senate race rating from "lean Republican" to "toss-up last month. On September 14, 2026, Ashley Hinson did not attend Vice President JD Vance's rally in Council Bluffs, Iowa, last week, citing a scheduling conflict. On that same day, I want to make a shoutout to an amazing public servant," Vance said in his remarks. On September 15, 2026, after the House vote, Grassley said he would continue supporting efforts to prevent Iran from obtaining a nuclear weapon. Also on September 15, the latest House resolution regarding the war with Iran passed 220-204 last Tuesday.

What's New

Hinson proposed expanding E-15, restoring the $1-per-gallon biodiesel tax credit, and creating a diesel relief program for farmers and truckers. Marianette Miller-Meeks outlined a six-point plan that includes suspending federal and state fuel taxes, temporarily stopping diesel exports, providing direct relief to farmers and truckers, expanding domestic drilling, allowing year-round E-15, and extending the biodiesel tax credit. "Through executive action, President Trump can provide immediate relief for Iowa family farmers feeling the squeeze by imposing a temporary diesel export ban," Grassley said.

"Iran’s nuclear threat puts Americans’ lives at risk, and national security is the number one responsibility of the federal government," he said in a statement. Marianette Miller-Meeks' plan calls for ending the open-ended war with Iran. Zach Nunn said Iran should be held accountable for killing Americans, supporting terrorism, threatening the Strait of Hormuz, and pursuing nuclear weapons. Agriculture Secretary Rollins said the president had discussed diesel relief and that an announcement could be coming soon.
