Trump Pressures Senate to Block Iran War Powers Resolution

The U.S. Senate narrowly blocked a war powers resolution on June 24, 2026, that would have restricted Donald Trump from continuing military operations in Iran without congressional authorization. The measure failed in a 47-50-1 vote, a sharp reversal from a Tuesday vote where the Senate had approved a similar non-binding resolution 50-48. The shift occurred after Republican Senators Bill Cassidy and Rand Paul changed their positions; Cassidy voted against the measure and Paul voted present.

The reversal followed a volatile closed-door lunch on Capitol Hill where the president berated GOP senators for their perceived disloyalty. During the meeting, Trump and Senator Cassidy engaged in a shouting match over the administration's lack of transparency regarding war objectives, with Trump reportedly calling Cassidy a "lunatic." Cassidy later flipped his vote after receiving a private White House briefing from Vice President JD Vance and Special Envoy Steve Witkoff.

This legislative battle coincided with broader tensions between the White House and Congress. Trump abruptly canceled the signing of the bipartisan 21st Century ROAD to Housing Act, demanding the Senate first pass the SAVE America Act, an election reform bill. Meanwhile, the administration continued to seek billions in supplemental funding to cover the costs of the conflict, which began with U.S.-Israeli strikes on February 28. Trump celebrated the final Senate vote on Truth Social, asserting that the outcome "puts Iran on notice!"
