Thune 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.
John’s attraction to public service took him to Washington, DC to work for U.S. Senator Jim Abdnor. He then served at the Small Business Administration under an appointment from President Ronald Reagan.
In 1989, John and his family returned to South Dakota, where he served as the Executive Director of the South Dakota Republican Party. In 1991, Governor George S. Mickelson appointed him the State Railroad Director, a position he held until 1993, when he became Executive Director of the South Dakota Municipal League.
In 1996, with a shoestring budget and the support of family and friends, John won his first term as South Dakota’s lone member of the United States House of Representatives. John was reelected to a second term by the largest margin in South Dakota history. He returned again to Washington in 2001 to serve his third term in the House.
Thune then honored his 1996 campaign pledge to serve only three terms in the House of Representatives. After a narrow loss in a Senate race in 2002, Thune won his Senate seat in 2004, when he made history by defeating a sitting Senate party leader for the first time in 52 years.
Thune serves on the Agriculture, Nutrition & Forestry Committee, the Armed Services Committee, the Commerce, Science & Transportation Committee, and the Small Business Committee.
John and his wife Kimberley live in Sioux Falls, South Dakota and have two daughters, Brittany and Larissa. Brittany is a college graduate and Larissa is a college junior. In his free time, John enjoys spending time with his family, pheasant hunting, and playing basketball.
