Trump clashes sharply with Republican senator during Iran briefing

WASHINGTON, United States — WASHINGTON — US President Donald Trump engaged in a heated verbal exchange with Louisiana Republican Senator Bill Cassidy during a working lunch focused on the ongoing conflict with Iran, according to Kansas Republican Senator Roger Marshall. Speaking to reporters, Marshall described the exchange as intense, comparing it to a hospital board meeting where "a group of doctors are yelling at each other but ultimately find a way to an agreement." Marshall said Trump was deeply disappointed by a Senate vote the previous day on war powers legislation related to Iran. The senator noted that Republicans believe the resolution weakened the administration's negotiating position in talks with Tehran. Administration officials view the congressional vote as a signal that could weaken US negotiators' leverage with Iran, Marshall added. The Senate vote, which advanced a resolution seeking to limit presidential military authority regarding Iran, has opened a new fault line between the White House and members of his own party as diplomatic and military pressure on Tehran continues.
