Agriculture and cost of living: Marshall said he led the Whole Milk for Healthy Kids Act, signed into law in January 2026, restoring whole and 2% milk to the National School Lunch Program. He said he introduced S. 4418 on April 28, 2026, to eliminate countervailing duties on phosphate fertilizer imports from Morocco, projecting a more than 20% cut in phosphate fertilizer costs, or roughly $150 per ton. Marshall said he voted for the Working Families Tax Cuts in 2025 to make the 2017 tax cuts permanent, including the small business deduction and expanded child tax credit.

Healthcare: Marshall said he leads the Improving Seniors' Timely Access to Care Act (S. 1816), setting 24- and 72-hour deadlines on Medicare Advantage prior-authorization requests. He said he introduced the Medicare Advantage Improvement Act in April 2026 to ban retroactive denials and automated denial algorithms. He also said he leads the Patients Deserve Price Tags Act (S. 2355), requiring hospitals and other facilities to publish upfront prices. Marshall said he opposes government-run healthcare and supports covering preexisting conditions.

Immigration and border security: Marshall said he cosponsored the Laken Riley Act (S. 5), signed into law Jan. 29, 2025, requiring ICE detention of unauthorized immigrants who commit certain crimes. He said he also cosponsors the Build the Wall Act (S. 42).

Defense and veterans: Marshall said he voted for the PACT Act in August 2022, expanding VA benefits for veterans exposed to burn pits and toxic substances. He said he cosponsors the Major Richard Star Act (S. 1032), which would end the offset forcing medically retired combat-injured veterans to choose between retirement pay and disability compensation.

Energy and environment: Marshall said he is an original cosponsor of the EQIP Water Conservation Act (S. 2696), directing the USDA to prioritize water-saving practices in stressed aquifer regions.

"All-of-the-above is the Kansas energy answer because it is the Kansas economic answer," Marshall said in a BallotReady questionnaire response.
