Mr. Rogers, who once led the House Intelligence Committee, is the most prominent Republican so far in the race to replace Senator Debbie Stabenow, a Democrat who is retiring.
Former Representative Mike Rogers of Michigan announced a campaign for an open Senate seat on Wednesday, giving Republicans a prominent candidate in an important swing-state race.
Mr. Rogers, 60, served seven terms in the House and rose to become the chairman of the House Intelligence Committee before leaving in 2015. He is by far the biggest name for the Republicans so far in the race to replace Senator Debbie Stabenow, a Democrat who is retiring.
“I thought I put politics behind me,” he said in a video announcing his campaign. “But like you, I know something is broken.”
He criticized President Biden’s policies and said “politicians are fighting over banning gas stoves while China is stealing our intellectual policy and our jobs.”
The seat is not one of Republicans’ foremost targets in 2024, when they need to flip one or two seats to regain control of the Senate, depending on whether they also flip the White House.
