Trump clashes with GOP senators over Iran vote and elections bill

Donald Trump walked into a Capitol lunch with Senate Republicans on Wednesday determined to push his SAVE America Act, then instead collided with the party’s own unease over Iran, congressional authority and his demands for loyalty. Hours after the Senate voted 50-48 on Tuesday, June 23, 2026, to pass a war powers resolution aimed at blocking further U.S. military action against Iran, Trump canceled a planned signing ceremony for a bipartisan housing affordability bill and used the lunch to press his agenda.

The meeting quickly turned tense, especially when Trump sparred with Sen. Bill Cassidy of Louisiana over the Iran vote. Trump repeatedly told Cassidy to sit down, and he called Cassidy a “lunatic.” The exchange came amid a broader fight inside the Republican Party, where Senate Democrats and a bloc of GOP lawmakers had just joined to curb Trump’s war-making leverage through Congress.

Senate Republicans had expected a wider conversation about the midterms and the party’s direction, not a confrontation over a vote that directly challenged Trump’s handling of Iran. Sen. Thom Tillis of North Carolina and Cassidy, both leaving the Senate and both under pressure from Trump-aligned politics, had already urged the party to move on from the SAVE America Act and focus on other priorities. Instead, Trump used the lunch to demand that Republicans circle around his elections overhaul bill and the grievances he carried into the room.

The clash also underscored the role of Senate Majority Leader John Thune, the party’s main intermediary as friction between Trump and Senate Republicans has deepened over nominees and policy fights. With the 2026 midterm campaign building, the lunch exposed how far Trump is still willing to test Senate discipline, and how publicly some Republicans are beginning to resist being folded into his agenda.
