=== 2016 campaign ===

Marshall ran against incumbent Tim Huelskamp in the Republican Party primary election for Kansas's 1st congressional district in the United States House of Representatives. He had the support of many of Kansas's agricultural groups, who were angry that Huelskamp lost his seat on the House Agriculture Committee, the first time in a century that no Kansan was on that panel. During the primary, Huelskamp's campaign ran TV ads criticizing Marshall for a confrontation with a neighbor in 2008 in connection with a land dispute; the neighbor made a 9-1-1 call accusing Marshall of attempting to run him over with a vehicle. Marshall ultimately pleaded no contest to a reckless driving misdemeanor and settled the neighbor's civil suit.On August 2, Marshall defeated Huelskamp in the Republican primary, 56% to 44%. No Democrat filed to run in the heavily Republican district.In the general election, Marshall won handily, defeating independent candidate Alan LaPolice and Libertarian Kerry Burt with 65.9% of the vote.
Marshall was endorsed by the United States Chamber of Commerce, the Kansas Livestock Association, the National Association of Wheat Growers, and the Kansas Farm Bureau, an affiliate of the American Farm Bureau Federation.Marshall represented a district that had long been nicknamed "the Big First" because it covered all or part of 63 counties in central and western Kansas, more than half the state's land mass. It was the seventh-largest district in the nation that did not cover an entire state.


=== Tenure ===
Marshall was sworn into office on January 3, 2017.On October 23, 2019, Marshall was part of a group of 15–30 House Republicans, led by Representative Matt Gaetz, who intruded upon that day's confidential hearing of the House Intelligence Committee. The Republican and Democratic committee members were meeting in a Sensitive Compartmented Information Facility (SCIF) to hear testimony from Deputy Assistant Secretary of Defense Laura Cooper in connection with the impeachment inquiry against Donald Trump.
