Democrat Chedrick Greene has won a special state Senate election in Michigan, NBC News projects, ensuring his party will keep control of the closely divided chamber.

Greene, a Marine veteran and firefighter, defeated Republican Jason Tunney, a former prosecutor, in the special election to replace Democratic U.S. Rep. Kristen McDonald Rivet, who resigned from the state Senate after she was elected to Congress in 2024.

Greene’s victory means Democrats will hold a 20-18 majority in the Senate. Democrats also control the governorship in Michigan, a key battleground state, while Republicans have a 58-52 edge in the state House.
