Cynthia Lummis is the junior United States Senator from Wyoming, having served in the Senate since 2021. A member of the Republican Party, she was born in Cheyenne, Wyoming, in 1954 and graduated from the University of Wyoming and its College of Law. Before her Senate career, she served as Wyoming State Treasurer, in the Wyoming State House and Senate, and represented Wyoming's at-large congressional district in the U.S. House of Representatives from 2009 to 2017. She was elected to the Senate in 2020 and became one of the first senators to publicly hold Bitcoin and to advocate for cryptocurrency on the Senate floor.
Lummis sits on the Senate Banking, Housing, and Urban Affairs Committee, where she has become the Senate's leading voice on cryptocurrency and digital asset regulation. She has focused on creating a clear regulatory framework for Bitcoin and other digital assets, ranching and agricultural policy, federal lands management, and fiscal conservatism. Her ownership of Bitcoin and her deep engagement with cryptocurrency policy have made her the most prominent congressional advocate for the digital asset industry in the upper chamber.
