Roger Marshall is an American politician and physician serving as the junior United States Senator from Kansas since 2021. A member of the Republican Party, he previously represented Kansas's 1st congressional district in the U.S. House of Representatives from 2017 to 2021. Before entering politics, Marshall had a distinguished career in medicine, specializing in obstetrics and gynecology, practicing for over 25 years in Great Bend, Kansas. He earned his undergraduate degree from Kansas State University and his medical degree from the University of Kansas School of Medicine, later completing his residency at Bayfront Medical Center in Florida. Marshall also became involved in local agriculture and business, reflecting his roots in the state's rural economy. His political career is marked by conservative positions, particularly on healthcare, agriculture, and social issues. As a senator, he serves on key committees including Health, Education, Labor, and Pensions (HELP), Agriculture, Nutrition, and Forestry, and Veterans' Affairs. He has been vocal on reforming healthcare policies, drawing from his medical background, and supports pro-life stances, including testimony in hearings on family-related legislation. Marshall has also advocated for farmers' interests and energy independence. His entry into politics was motivated by concerns over federal overreach in healthcare following the Affordable Care Act. Despite his relatively short time in Washington, he has built a network within Republican circles, focusing on Midwestern priorities.
