WASHINGTON — For the second time in as many weeks, a War Powers Resolution aimed at curbing President Donald Trump’s war with Iran failed to pass the U.S. Senate Thursday.

The vote breakdown, 49-50, fell along familiar lines as previous War Powers votes, with Republican Sens. Lisa Murkowski of Alaska, Rand Paul of Kentucky and Susan Collins of Maine supporting the measure.

Democratic Sen. John Fetterman of Pennsylvania voted no, as he’s done in just over a dozen similar measures.

Sen. Mitch McConnell, R-Ky., continues to be absent while in medical rehab.

A similar War Powers Resolution to rein in Trump’s military conflict in Iran passed in the U.S. House on July 23, but failed in the Senate — both led by Republican majorities.

The regional war reignited yet again this week after Trump ordered retaliatory strikes Tuesday, along with Saudi Arabia’s armed forces, on Iran-backed militias in eastern Iraq. The strikes on “multiple terrorist logistics and weapons sites” were in response to Iranian drone attacks on U.S. forces in the region, according to U.S. Central Command.

Trump told Fox News on Wednesday, “We are going to beat the f—– s—- out of them.”

The United States launched a “heavy wave” of strikes on Iranian military sites beginning at 10 p.m. Eastern Wednesday “in response to yesterday’s attempted missile attacks on U.S. forces,” according to U.S. Central Command.

The cost of oil jumped to just over $90 a barrel Wednesday in response to renewed fighting and a continued chokehold on traffic through the Strait of Hormuz, where one-fifth of the world’s petroleum traveled prior to the U.S. and Israel launching the war in late February.

This means Americans are again paying more for fuel. According to AAA, the U.S. national average for a gallon of regular gasoline rose to $4.09 Thursday.

Before the volley of strikes began again, Trump had announced a pause, after the U.S. and Iran traded rocket fire for nearly two weeks following the collapse of ceasefire talks.

The president on July 22 attended the dignified transfer, in which the remains of soldiers are transferred from an aircraft arriving from the theater of operations back to the United States, for four U.S. service members killed as a result of the conflict with Iran.

Three of the service members were killed July 17 and July 18 in an Iranian strike at a U.S. airbase in Jordan, and a fourth was killed during a controlled detonation of an Iranian drone July 19 at a U.S. base in Iraq.

The most recent deaths of U.S. soldiers in the conflict bring the total killed to 18, while the number of injured increased to 653.

But the Pentagon does not recognize the four most recent deaths among those in the Iran war, dubbed by the administration as Operation Epic Fury.

Instead, the Pentagon is categorizing the latest deaths and injuries as casualties of “overseas operations starting July 7, 2026.”

The administration is asking Congress for an additional $67 billion for the war in Iran. Defense Secretary Pete Hegseth told Senate appropriators July 21 that the war has already cost $37.5 billion.
