Jonathan "Jon" Tester (born August 21, 1956) served as the senior United States Senator from Montana from 2007 to 2025. He is a member of the Democratic Party.
Tester was first elected to the Senate in 2006, beating Republican incumbent Conrad Burns in one of the closest Senate races of that year. He won re-election in 2012 against Rep. Denny Rehberg in another close race.
Tester previously served as the president of the Montana Senate and worked as a music teacher and farmer. He became the senior Senator in 2014 when Max Baucus resigned to become U.S. ambassador to China.
Tester lost his re-election campaign to Republican businessman Tim Sheehy in November 2024.
At the age of nine, he lost the middle three fingers of his left hand in a meat-grinder accident.[1]
