Did Bill Cassidy shout at Trump?

Yes, Senator Bill Cassidy engaged in a heated shouting match with President Donald Trump during a closed-door Senate Republican Steering Committee lunch at the U.S. Capitol on June 24, 2026. Multiple attendees and Cassidy himself confirmed that voices were raised as they clashed directly over the administration's handling of the war in Iran.

Key Details of the Confrontation

• The Catalyst: The argument broke out after Trump questioned why Republican senators had voted for a war powers resolution to limit his military authority in Iran.
• The Exchange: Cassidy stood up and challenged Trump, stating that the American people were not being told the truth about a conflict that was supposed to last four weeks but has stretched into four months.
• The Escalation: When Trump became angry and raised his voice, Cassidy acknowledged that he lost his temper and "matched his tone and his volume" in a back-and-forth screaming match.
• Insults and Retorts: During the argument, Trump repeatedly ordered Cassidy to sit down and called him a "lunatic" and a "loser". In an effort to de-escalate the tension while refusing to be bullied, Cassidy repeatedly addressed the president as "brother" instead of "Mr. President," prompting Trump to snap back that he was not his brother.

Background and Aftermath

The public flare-up follows long-festering political enmity. Cassidy, who voted to convict Trump during his 2021 impeachment trial, was recently ousted in a Louisiana Republican primary election by a Trump-backed challenger. Observers noted that since losing his primary, Cassidy has been far more willing to openly confront the president.

Hours after the shouting match, Cassidy switched his vote on a subsequent Iran war powers resolution after receiving an immediate briefing from Vice President JD Vance.
