President Trump called Sen. Bill Cassidy "a disloyal disaster" and "a terrible guy" on Saturday, backing Rep. Julia Letlow in Louisiana's Republican primary against the Senate Health Committee chair, according to STAT News. Cassidy's campaign and a supporting super PAC spent a combined $21.9 million on the race through Saturday, compared to roughly $9.9 million between Letlow's campaign and her backing PAC, per ad-tracking firm AdImpact; if no candidate clears 50 percent, a runoff is scheduled for June 27.
