US President Donald Trump faced pointed criticism over the Iran war in a closed-door meeting with fellow Republicans, shortly before his administration asked Congress for tens of billions of dollars to pay for the conflict, Reuters reports.

Several Republicans in the closed-door meeting said Trump engaged in a shouting match with Republican Senator Bill Cassidy, who said the administration needed to explain a framework deal Trump signed last week that provides financial incentives for Iran but does not accomplish any of the goals he laid out at the war’s beginning.

“The American people need to know more than we are being told,” Cassidy told reporters. “It does not appear, although I don’t know for sure, that the course of this is going the way that we were told.”
