Former President Donald Trump congratulated U.S. Representative Julia Letlow on Truth Social after she won the Republican runoff in Louisiana’s U.S. Senate race, defeating state Treasurer John Fleming. Letlow will face Democratic nominee Jamie Davis in the November general election for the seat currently held by Senator Bill Cassidy, who was eliminated in the May primary. Trump had endorsed Letlow, who also received backing from Governor Jeff Landry and House Majority Leader Steve Scalise. The race matters because Louisiana is a heavily Republican state that Trump carried by 22 points in 2024, making Letlow the strong favorite to win Cassidy’s seat.
