Mr. Rogers, 60, served seven phrases within the House and rose to grow to be the chairman of the House Intelligence Committee earlier than leaving in 2015. He is the largest identify for the Republicans thus far within the race to switch Senator Debbie Stabenow, a Democrat who is retiring. Peter Meijer, a one-term consultant who was among the many 10 Republicans who voted to question President Donald J. Trump, also joined last week.

“I thought I put politics behind me,” Mr. Rogers said in a video announcing his campaign. “But like you, I know something is broken.”

The seat just isn’t one among Republicans’ foremost targets in 2024, when they should flip one or two seats to regain management of the Senate, relying on whether or not additionally they flip the White House. Those high targets are Montana, Ohio and West Virginia, all of which voted for Donald J. Trump twice and select Republicans in most statewide elections.

But Michigan is a second-tier goal provided that it voted for Mr. Trump in 2016 and was intently contested in 2020. It swung towards Democrats in the midterms, nonetheless — Gov. Gretchen Whitmer received re-election by greater than 10 share factors, and Democrats received three out of 4 aggressive House races and flipped each chambers of the State Legislature — and the Michigan Republican Party has fallen into disarray.

Against that backdrop, Mr. Rogers, along with his political expertise and identify recognition, might give Republicans a extra sensible shot than the lesser-known candidates within the discipline.

The Democratic discipline is headlined by Representative Elissa Slotkin, who was elected to Congress within the blue wave of 2018 and has received re-election twice in a swing district. Her major opponents embody the actor Hill Harper; Nasser Beydoun, a businessman; and Pamela Pugh, the president of the State Board of Education.

Mr. Rogers — no relation to the Alabama consultant and House Armed Services Committee chairman of the same name — spent a number of years as a particular agent for the F.B.I. earlier than operating for the State Senate after which Congress. That expertise helped make him one of many House’s most distinguished voices on nationwide safety. Before his retirement, he was a frontrunner in negotiations with President Barack Obama to overtake the National Security Agency’s digital surveillance applications.
