Sen. Bill Cassidy loses GOP primary in Louisiana, as two rivals advance to a runoff

Key Points:

• Sen. Bill Cassidy, who voted to convict Donald Trump in the 2021 impeachment, lost the Louisiana Republican primary, with Trump-endorsed Rep. Julia Letlow and state Treasurer John Fleming advancing to a runoff on June 27.
• Cassidy’s loss underscores Trump's influence over the GOP and marks another defeat for Republicans who opposed Trump during his impeachment. Trump celebrated Cassidy’s defeat as a consequence of his "disloyalty."
• Cassidy criticized Trump’s false election fraud claims in his concession speech, emphasizing loyalty to the Constitution and the welfare of Americans over any individual leader.
• Letlow, backed by Trump and Louisiana Gov. Jeff Landry, positioned herself as the pro-Trump conservative alternative, while Fleming, also a Trump ally but without the endorsement, self-funded much of his campaign.
• The runoff outcome remains uncertain, with Trump’s further involvement unclear as his political focus shifts to other key races; Republicans are favored to retain the Senate seat in the heavily GOP state.
