Some who worked for Stevens’ campaign also reportedly quit following her endorsement of Rogers

Congresswoman Haley Stevens, who lost the Michigan Democratic Senate primary to Abdul El-Sayed, endorsed his Republican rival, Mike Rogers, in an extraordinary rebuke of her party’s nominee on the eve of the midterm elections.

Her endorsement came in a video posted to X after she attended an event with Rogers at the predominantly Black Perfecting church in Detroit on Sunday. Stevens’s endorsement was the culmination of an escalating feud between the former primary rivals that has roiled one of the most fiercely contested Senate contests of the cycle.
