Senate Republicans Reject War Powers Resolution After Trump Pressure
President Trump faced off with Senate Republicans over military action in Iran, culminating in a dramatic reversal that underscores deepening tensions between the White House and GOP lawmakers.
The conflict began when Senate Republicans allowed a vote on a war powers resolution to block Trump's Iran operations. Angered by this defiance, Trump summoned GOP senators to a contentious lunch on Capitol Hill where he berated them over their opposition to his military strategy.
The confrontation grew particularly heated between Trump and Louisiana Senator Bill Cassidy, one of four Republicans who voted with Democrats on the measure. Trump questioned why anyone would support the War Powers Act. Cassidy responded directly, asking whether the question was rhetorical or genuine.
Despite the tense exchange, Cassidy's position shifted dramatically hours later. After receiving a personal briefing at the White House from Vice President JD Vance and Special Envoy Steve Witkoff, Cassidy returned to Capitol Hill and voted against a nearly identical war powers resolution that came up for a separate vote that evening.
"I want to thank Vice President Vance and Special Envoy Witkoff for the thorough briefing this afternoon on Iran," Cassidy posted on social media afterward. "I appreciate the quick invitation to the White House to address many of my concerns."
Republican Senator Rand Paul of Kentucky also shifted his stance, voting present on the second measure "to give the President more space and leverage to negotiate a lasting peace," according to his social media statement. Paul had previously voted with Democrats on the initial resolution.
The second war powers measure failed 47-50-1 just before midnight Wednesday, after which the Senate departed for a two-week recess. Senate Majority Leader John Thune and other GOP colleagues called Trump following the vote. Thune reported to reporters that Trump was "pleased with the outcome."
Trump subsequently thanked Thune in a social media post, noting that Cassidy and Paul had changed their positions. "This vote puts Iran on notice!" Trump wrote.
The two war powers votes occurred on separate tracks but addressed nearly identical concerns. Both measures were largely symbolic and do not carry the full force of law. The first passed the House and was then blocked by the Senate on Tuesday, followed by the second failed Senate vote on Wednesday.
The disputes over Iran policy form part of a broader disagreement between Trump and Senate Republicans. The two sides also remain at odds over extending surveillance authorities and Trump's push to eliminate the Senate filibuster to advance his legislative agenda, a proposal many Republican senators oppose as it would undermine their ability to block future Democratic initiatives.
