Gary Peters is the senior United States senator from Michigan, serving since 2015. Before the Senate, he represented Metro Detroit in the U.S. House and served in Michigan state government, building a reputation as a policy-focused Midwestern Democrat with a technocratic style.
Born December 1, 1958 in Pontiac, Michigan, Peters worked for years as a financial professional and also served in the U.S. Navy Reserve, ultimately reaching the rank of lieutenant commander. He later brought that management-and-oversight mindset into public office.
Peters climbed through Michigan politics: Rochester Hills City Council, the Michigan Senate, then a statewide run for attorney general. He later served as Michigan Lottery commissioner before winning a U.S. House seat in 2008 and then the Senate in 2014.
In the Senate, Peters’ brand has been competence and oversight: cybersecurity, supply chains, veterans issues, election security, and Great Lakes protection. He has held major leadership responsibilities in Senate campaign politics and has been a high-visibility committee leader on homeland security and government accountability.
