Trump Urges Republicans to Vote Out Sen. Cassidy in Louisiana Primary — Endorses Challenger Julia Letlow

On May 16, 2026 — the date of the Louisiana Republican primary — President Trump publicly called for all Republicans to vote out Sen. Bill Cassidy (R-LA), endorsing challenger Julia Letlow instead. Cassidy has been a persistent thorn for Trump allies since voting to convict Trump at the second impeachment trial in February 2021. The Louisiana primary is part of Trump's broader effort to reshape the Republican Party in his image by supporting primary challengers against any Republican who challenged him. Letlow, a congresswoman from Louisiana's 5th district, was seen as a solidly MAGA-aligned alternative.
