Trump Criticizes Bill Cassidy and Backs Julia Letlow in Louisiana Primary

Outlets agree that Trump criticized Sen. Bill Cassidy and backed Rep. Julia Letlow in Louisiana’s Republican Senate primary. Left-leaning outlets link Trump’s attack and endorsement to Cassidy’s impeachment vote, while one article instead covers Trump’s separate disputes with Lauren Boebert and Thomas Massie. Center outlets generally pair Trump’s role with candidate and election context, though two articles cover the Boebert-Massie disputes instead. Right-leaning outlets connect Trump’s attack to Cassidy’s impeachment vote and the risk to Cassidy’s seat.
