Republican former U.S. Rep. Mike Rogers of White Lake and Democratic U.S. Rep. Elissa Slotkin of Holly are locked in a tight race for Michigan's open U.S. Senate seat.

U.S. Representative Elissa Slotkin, a third-term lawmaker with extensive national security experience, won election to the U.S. Senate in Michigan, Edison Research projected on Wednesday, a boost for Democrats trying to hold their majority in the chamber.

Democratic Sen. Jon Tester faced challenger Tim Sheehy in a highly consequential race for the Senate’s balance of power.
