Democratic Representative Haley Stevens of Michigan has sparked widespread party backlash after breaking ranks to endorse Republican Senate nominee Mike Rogers ahead of the 2026 midterm elections.

The unexpected endorsement follows days of public and private tension between Stevens and the Democratic Senate nominee, Abdul El-Sayed, who defeated Stevens in a competitive primary. The rift culminated when Stevens appeared alongside Rogers at a church service in Detroit. The move drew swift condemnation from national and state Democratic leaders, including Michigan Representative Debbie Dingell and state Senator Mallory McMorrow, who criticized the endorsement as a self-serving distraction.

The fallout also hit Stevens' congressional office directly, with her chief of staff and communications director among several staffers who resigned in the wake of the announcement. In response to questions about her alignment with Rogers amid GOP attacks on El-Sayed's faith, Stevens maintained that her decision was not anti-Muslim and praised Michigan's Muslim American community.

Despite the high-profile intraparty fracture in a critical battleground race for control of the Senate, top Democrats have firmly rallied behind El-Sayed, leaving open whether primary voters will follow Stevens' lead.
