Kamala Harris' presidential campaign announced endorsements from over two dozen former Republican officials, including some who served in the Trump administration, like Stephanie Grisham and Olivia Troye. Other Republican endorsers included former cabinet members Chuck Hagel and Ray LaHood, who served under President Obama. The Harris campaign launched a new "Republicans for Harris" initiative to highlight these crossover endorsements as she works to appeal to Republican voters. Donald Trump called for the removal of dissenters within his party. He criticized former Georgia lieutenant governor Geoff Duncan for endorsing Harris, labeling him as a "loser," in a Truth Social post.
