DETROIT (AP) — Michigan Democrat Abdul El-Sayed’s former opponent in the U.S. Senate primary, Haley Stevens, has stunned party officials by endorsing Republican Mike Rogers. The development Sunday comes as Democratic tensions have boiled over days before the election that could determine the balance of power. Stevens endorsed Rogers after attending a Detroit church service with him. The remarkable show of support for President Donald Trump’s endorsed candidate comes after she was uninvited to a joint event the same day with El-Sayed. Keeping Michigan in Democratic hands is vital to the party’s effort to win a majority. El-Sayed dismissed the endorsement, saying he’s focused on issues voters care about.
