Overview
- Senate GOP leaders John Thune and Tim Scott endorsed Andy Barr on Monday, following Friday's Trump endorsement that reordered the primary.
- Trump asked businessman Nate Morris to step aside with an ambassadorship offer that did not specify a post, and Morris, who had Elon Musk's financial backing, exited and endorsed Barr.
- Barr spent Monday touting Trump's backing across Kentucky, telling supporters he would work to earn every Republican vote before primary day.
- Former Attorney General Daniel Cameron remains in the race and told supporters he expects to win the May 19 nomination.
- Late-March polling showed Barr leading Cameron by about seven points, and the open seat from Mitch McConnell's retirement sits in deep-red Kentucky as Republicans defend a 53–47 Senate majority.
