Trump had vowed earlier Wednesday to block a bipartisan affordable housing bill Congress had given final passage to the night before, declining to sign the bill and fueling panic from lawmakers. Just hours later, Republicans were gathered together when the reported clash between the president and the longtime GOP lawmaker, who lost his re-election to a Trump-endorsed candidate, came to a head.
Several political reporters recounted the moment.
MS NOW congressional correspondent Mychael Schnell described the unusual incident.
“Sen. Bill Cassidy (R-La.) confronted President Trump over the Iran memorandum of understanding, a source familiar with the lunch conversation tells me @MSNOWNews,” Schnell wrote in a post on X. “Cassidy was ‘yelling’ at Trump, the source said. This source also tells me that Trump went after Sen. Dave McCormick (R-Pa.) for missing yesterday’s war powers vote, which was successful, 48-50. But worth noting: McCormick was with Trump at a Pennsylvania rally. And even if he were at the Capitol, the resolution still would’ve been successful because McConnell was absent.”
Semafor congressional bureau chief Burgess Everett broke down what allegedly happened.

“The Senate GOP meeting with Trump is not going well. ‘A total cluster f—‘ one person said,” Everett wrote on X. “Trump is mad about the war powers resolution passing yesterday and he and Cassidy are going after each other.”
Punchbowl News senior congressional reporter Andrew Desiderio detailed the scene.
“Trump and Cassidy just went at each other over Iran during the Senate GOP lunch, per source in room (sic). Trump was interrupting Cassidy as Cassidy was calling the war a ‘blunder.’ Other senators tried to jump in, but Cassidy & Trump kept going back & forth, source said,” Desiderio wrote on X.
