A closed-door meeting between U.S. President Donald Trump and Senate Republicans at the Capitol on Wednesday turned confrontational after a heated exchange with Sen. Bill Cassidy, highlighting growing divisions within the Republican Party over the administration’s handling of Iran and its broader legislative agenda.
The dispute unfolded during a roughly 70-minute luncheon attended by Republican senators, where Trump questioned members of his party who had supported a Senate measure seeking to limit the president’s military authority regarding Iran. Cassidy, a Louisiana Republican, challenged the president over the administration’s strategy, saying lawmakers and the public had not received sufficient information about the operation or its objectives.
Speaking after the meeting, Cassidy said he told Trump that the administration had not adequately explained developments surrounding the military effort, arguing that its duration had exceeded initial expectations and that key objectives had yet to be achieved. The senator said the disagreement quickly escalated, with both men raising their voices during the exchange.
People familiar with the meeting said Trump urged Cassidy to sit down during the confrontation, but the senator initially refused. The president reportedly called Cassidy a “lunatic” before the exchange eventually subsided. Cassidy later said fellow senators encouraged him to de-escalate the situation, prompting him to take his seat.
Despite the confrontation, Cassidy changed his position later in the day on a separate procedural vote involving a similar Iran war powers resolution. His vote helped Republican leaders prevent the measure from advancing.
Following that vote, Cassidy said he had received a detailed briefing from Vice President JD Vance and Special Envoy Steve Witkoff that addressed many of his concerns. In a post on X, he also said he appreciated an invitation to the White House for further discussions.
The tense meeting reflected broader disagreements within the Republican conference as some lawmakers express concern over the administration’s approach to foreign policy and congressional consultation. Trump’s frustration was reportedly directed not only at Cassidy but also at other Republican senators who had either supported the earlier Iran-related measure or were absent during the vote.
Sen. John Kennedy of Louisiana told reporters after the meeting that the president remained deeply upset over the Senate’s action on the war powers resolution.
Although Trump later described the gathering as having gone “really great,” he acknowledged there were individuals within the party with whom he disagreed.
Beyond foreign policy, much of the discussion centered on Trump’s legislative priorities, including the SAVE America Act, an elections proposal the president continues to advocate despite concerns from Senate Republicans that it lacks sufficient support to pass.
Sen. Rick Scott of Florida said he informed Trump that the current vote count does not favor the legislation, adding that lawmakers must recognize political realities. Trump, however, continued pressing senators to pursue the measure.
Senate Majority Leader John Thune also indicated that Republican leaders have repeatedly explained the bill’s limited prospects in the Senate, though it remained unclear whether the president accepted that assessment.
The meeting came as Republican leaders seek to shift attention toward domestic priorities, including cost-of-living issues, while navigating internal disagreements over strategy ahead of upcoming elections. Some lawmakers have privately expressed concern that continued disputes over issues with limited legislative support could complicate the party’s broader political objectives.
Sen. John Cornyn of Texas, who is also preparing to leave the Senate after losing a Republican primary backed by Trump, remarked afterward that the president concluded the meeting by calling for party unity despite spending much of the session criticizing fellow Republicans.
The confrontation underscored ongoing tensions between Trump and some members of his own party as Senate Republicans continue balancing support for the president with disagreements over national security decisions and legislative priorities. No further meetings between Trump and Cassidy were immediately announced.
