Senate Republicans blocked a war powers resolution on Thursday that would have directed President Donald Trump to withdraw U.S. troops from Iran. The vote was 49-50 to defeat the resolution to discharge the measure, falling short of the simple majority needed to advance.

The resolution, sponsored by Sen. Kirsten Gillibrand (D-N.Y.), aimed to force a withdrawal from what has been reported as a war that began five months ago. The conflict has raised concerns about energy prices and the depletion of key missile defense systems.

49-50

Senate vote to defeat the discharge resolution on the war powers measure.

A report from the Center for Strategic and International Studies (CSIS) found that Patriot interceptor missiles dwindled from 2,330 to 759 and THAAD interceptor missiles from 452 to 234, highlighting the strain on U.S. defenses.

Sen. Thom Tillis (R-N.C.) said he has not been adequately briefed on munitions, indicating unease among some Republicans. Sen. Richard Blumenthal (D-Conn.) stated that President Trump launched the Iran war impulsively without a clear set of achievable objectives and planning.

Growing discomfort among Senate Republicans over the expansion of the Iran war was reported, though the party largely stood with the president. The war's impact on energy prices has also been noted.
