U.S. Rep. Julia Letlow won the Republican nomination for U.S. Senate in Louisiana on Saturday, giving Donald Trump a win after he backed her to replace GOP Sen. Bill Cassidy.

Letlow, who was endorsed by Trump, defeated state Treasurer John Fleming in the two-candidate runoff after they finished ahead of Cassidy in the GOP primary May 16.

Letlow pledged her loyalty to Trump in a race where Cassidy, who voted to convict the president on impeachment charges in 2021, spent a year working to keep Trump from going after him. She has promised to work in lockstep with Trump to advance his agenda.
