Roger Marshall
Before he was Senator Marshall, thousands of Kansas families knew him as the doctor who delivered their babies.
Biography
Roger Marshall spent more than 25 years delivering babies in Great Bend, with more than 5,000 deliveries in his obstetrics and gynecology career.1 He and his wife, Laina, have four children and five grandchildren, and taught Sunday school together for more than 25 years.1 Away from politics, he enjoys time at the family farm and Kansas wildlife refuges.1
Raised in a Butler County farming family, Marshall became the first in his family to attend college, studying at Butler Community College, Kansas State and the University of Kansas medical school.1 He also served seven years in the Army Reserve.1 His community work has included coaching youth sports and serving as a Rotary district governor.1 He entered the House in 2017 and the Senate in 2021.2
In Washington, Marshall supported the 2025 Republican tax and spending law and has proposed requiring upfront prices for medical services.3 His proposed Lowering Healthcare Costs for Americans Act also calls for identity verification and minimum monthly payments for Affordable Care Act marketplace coverage.3
Marshall's current priorities include Medicaid work requirements, medical price transparency, tax relief and limits on large investors purchasing homes.3 He has backed Trump's tariffs.3 His opponent, Democratic pastor Adam Hamilton, is campaigning to reverse Medicaid cuts and end those tariffs.3
Record and controversies
Medical debt collection
A September 2026 New York Times investigation, discussed with its reporter by KCUR, identified more than 700 patients sued over medical debt by Marshall's practice before his congressional career.4 CNN reported annual interest of 18 percent and arrests of some patients after they missed court appearances.5 Marshall said the hospital provided millions in charity care and wrote off hundreds of bills monthly.5 CNN's fact check found that no law required the lawsuits and that financial hardship waivers were permitted, contrary to Trump's defense of the collection practices.5
Official resources and campaign work
In October 2026, End Citizens United asked the Senate Ethics Committee to investigate allegations that Marshall used official travel funds and congressional staff for campaign activities.6 A joint Kansas Reflector and MS NOW investigation reviewed records and staff accounts; Marshall's campaign lawyer said his team complied with election and Senate ethics rules and attributed the allegations to a disgruntled employee.7 The request for an investigation is not a committee finding.6
Historical driving case
Marshall faced misdemeanor battery and reckless driving charges after a 2008 property dispute; the battery charge was dropped, and he pleaded no contest to reckless driving before a later court order reduced it to a traffic infraction.8 In 2020, reporting identified the prosecutor as the son of Marshall's business partner; Marshall said he had not known who the prosecutor was and described the connections as part of life in a small city.8
