Former Transportation Secretary Pete Buttigieg is expected to announce he will not run for Michigan’s open Senate seat. During an appearance last month on CBS’s The Late Show with Stephen Colbert, Buttigieg revealed he was “looking” into launching a bid to replace retiring Sen.

One likely Republican candidate is Mike Rogers, who narrowly lost to Democrat Elissa Slotkin in an open U.S. Senate contest last year. Other Republicans considering bids are Rep. Bill Huizenga of Holland Township and 2022 gubernatorial nominee Tudor Dixon of Norton Shores.

SAUGATUCK, Mich. (AP) — Former Transportation Secretary Pete Buttigieg announced that he will not seek an open U.S. Senate seat in Michigan, a move that leaves the door wide open for him to seek a much bigger role as his party’s next presidential nominee.
