Washington — CBS News projects Rep. Julia Letlow and Louisiana state Treasurer John Fleming advanced to a runoff in Saturday's Senate Republican primary, knocking out incumbent GOP Sen. Bill Cassidy.
Cassidy, 68, was one of seven Senate Republicans who voted to convict President Trump in his impeachment trial after the Jan. 6 attack on the Capitol in 2021. And although he's emphasized his cooperation with the administration in recent years, the president endorsed Letlow in January, encouraging her to challenge Cassidy for the seat.
Mr. Trump took to Truth Social late Saturday night to congratulate Letlow, saying she ran "a fantastic race, beating an Incumbent Senator by Record Setting Numbers."
"Letlow is a fantastic person and, after taking care of some additional business, will make a brilliant Senator for the Great People of Louisiana, a State that I love, helped make prosperous with my Energy Policies and everything else," Mr. Trump wrote.
In a follow-up post , he accused Cassidy of "falsely using his 'relationship' with me during his political career, and winning Elections because of it," adding that Cassidy "voted to impeach me on preposterous charges that were fake then, and now, are criminally insane!"
