John Thune grew up in Murdo, South Dakota. His interest in politics was sparked at a young age after making five of six free throws during a freshman high school basketball game. He was later greeted by a spectator who said, “I noticed you missed one.” That spectator happened to be a well-known sports enthusiast and then-South Dakota U.S. Rep. Jim Abdnor. The introduction was the start of a friendship that ignited John’s career in public service.

John received his undergraduate degree at Biola University and his master’s degree in business administration from the University of South Dakota. Upon completion of his master’s degree in 1984, he married Kimberley Weems, a native of Doland, South Dakota.
