The Senate on Tuesday voted 50 to 47 to advance a war powers resolution to limit President Trump’s action in Iran.
Senator Bill Cassidy (LA) joined the Democrats after he lost his primary on Saturday amid Trump’s RINO revenge tour.
GOP Senators Collins and Paul also joined the Democrats.
Three GOP Senators – Cornyn, Tuberville and Tillis did not vote.
The Senate advanced a resolution to limit President Trump’s war powers in Iran on Tuesday, marking a breakthrough for Democrats after seven failed attempts.
Senators approved a motion to discharge the resolution from committee in a 50 to 47. Four Republicans — Sens. Susan Collins of Maine, Lisa Murkowski of Alaska, Rand Paul of Kentucky and Bill Cassidy of Louisiana — joined the bulk of Democrats in favor of advancing the resolution. Sen. John Fetterman of Pennsylvania was the sole Democrat to oppose.
The vote marked the first time Cassidy supported advancing a war powers resolution. It came days after he failed to win enough support to advance to a runoff in the Louisiana GOP Senate primary, where Mr. Trump endorsed one of his opponents.
And three Republicans — Sens. John Cornyn of Texas, Tommy Tuberville of Alabama and Thom Tillis of North Carolina — did not vote, tipping the scales in Democrats’ favor for the first time since they began bringing war powers resolutions related to Iran.
The war powers resolution was introduced by Democrat Senator Tim Kaine.
The resolution will order President Trump “remove the United States Armed Forces from hostilities within or against Iran, unless explicitly authorized by a declaration of war or a specific authorization for use of military force.”
“It’s been 80 days since Trump launched his illegal war against Iran,” Kaine said ahead of Tuesday’s vote.
“Congress has the power to slam the brakes on this unwise conflict. Today should be the day when the Senate tells the President to stop his disastrous war,” he said.
