President Donald Trump and Sen. Bill Cassidy, R-La., reportedly traded fierce barbs over the Iran war during a closed-door lunch with Senate Republicans.

Cassidy and Trump have been at loggerheads after the president endorsed Rep. Julia Letlow, R-La., in the Senate primary, ultimately contributing to Cassidy's elimination from the contest. But Cassidy has been in Trump's crosshairs since his 2021 vote to convict him in his second impeachment trial.

Speaking to reporters afterwards, Cassidy told lawmakers that Trump had berated lawmakers over a Senate vote on a war powers resolution demanding an end to the Iran war. When Trump asked for an explanation, Cassidy said that he offered his own.

“I stood and said, ‘You have not told the American people what’s going on. It was supposed to last four weeks, it’s lasted four months. Our original objectives have not been achieved and I want to know what’s going on,’” he said, according to The Hill.

The Iran war began in late February, with Trump calling for the end of Iran's nuclear program, regime change, and promising a swift end to the conflict. At present, negotiations are ongoing to reach an agreement to end the war, which appears to include very limited concessions to the U.S. war goals.

Polling data has shown the public overwhelmingly favors an immediate end to the Iran war rather than a continued war effort to extract greater concessions. The conflict also coincided with a precipitous drop in Trump's approval rating, which has rebounded modestly amid negotiations to end the conflict.
