U.S. Rep. Julia Letlow, backed by President Donald Trump, defeats Louisiana State Treasurer John Fleming in the Republican Senate runoff, multiple outlets project. The contest follows a May 16 GOP primary in which Letlow and Fleming finish ahead of incumbent Republican Sen. Bill Cassidy. Cassidy had been a target of Trump after Cassidy voted to convict Trump during the president’s 2021 impeachment trial. Sources describe Letlow’s campaign as largely aligned with Trump’s endorsement and wider effort to replace Republicans who break with Trump. After the primary left no candidate with a majority, Letlow and Fleming advance to the runoff, where Letlow wins the party nomination for Cassidy’s seat. The outlets characterize the result as another win for Trump’s preferred candidates in Republican nomination contests.
