Barrasso, John

John Barrasso is Wyoming's senior U.S. Senator and a member of the Republican Party serving since 2007. In 2025, he became Senate majority whip, the second-ranking position among Senate Republicans. As chair of the Taxation and IRS Oversight subcommittee under the Senate Finance Committee and the Public Lands, Forests, and Mining subcommittee under the Senate Committee on Energy and Natural Resources, Barrasso wields significant influence over tax policy and public lands management—two areas central to Republican priorities and Wyoming's economic interests.

Barrasso brings substantial professional credentials to these roles. A board-certified orthopedic surgeon who practiced medicine in Casper, Wyoming for over two decades, he also served as president of the Wyoming Medical Society and volunteered as a team physician for local schools and the Professional Rodeo Cowboys Association. Before his U.S. Senate career, he served in the Wyoming State Senate from 2003 to 2007. His medical background and Wyoming roots inform his approach to healthcare and natural resource policy, areas where he maintains active committee involvement.

As a senior Republican leader, Barrasso has sponsored legislation spanning healthcare access, fiscal responsibility, and natural resources management, including the Grasslands Grazing Act of 2025 and measures addressing rural broadband and rare diseases. He has been the dean of Wyoming's congressional delegation since 2021. His trajectory from a narrow primary loss in 1996 to his current position as majority whip reflects his standing within the Republican caucus and his influence over the Senate's legislative agenda.
