In a statement, Cheney said her endorsement in the competitive and open Senate race “is not about policy differences” but rather “about doing what is right for our country.”

“The stakes in this election are unlike anything we’ve faced before, but the future of our democracy is on the line,” Cheney, a former member of the House GOP leadership, said in Wednesday’s announcement.

“At a time when our democracy is being challenged, Liz Cheney’s voice has been critical,” Slotkin said in a statement, adding, “While we certainly don’t agree on every issue, I look forward to welcome back to Michigan next week. to talk about issues where all Americans can come together.”

Monday night’s event won’t be Cheney’s first time on the campaign trail with Slotkin. She endorsed the Michigan Democrat two years ago for Congress, the first time Cheney has ever endorsed a candidate across party lines. This year, of course, she endorsed Harris over Trump in the presidential race.

At a 2022 event in Slotkin’s congressional district, Cheney urged voters to “look beyond partisan politics” for the “survival of our republic” — a tone the Wyoming Republican struck during a series of appearances with Harris this week .

Earlier this month, Cheney endorsed Democrats in a pair of contested House races in New York and Pennsylvania that could hamper Republicans’ chances of retaining power in the lower house.
