Senate Push to Limit Trump’s Iran War Powers as Conflict Expected to Last Weeks

WASHINGTON — As U.S. military operations against Iran intensify, Sen. Tim Kaine, D-Va., plans to force a Senate vote this week aimed at restricting President Donald Trump’s ability to continue the conflict without explicit approval from Congress. The move comes as the president warns the fighting could stretch on for weeks and after the first American combat deaths were reported.

The debate is shaping up to be a major test of Congress’ constitutional role in authorizing war, a recurring flashpoint in Washington dating back to conflicts in Iraq and Afghanistan.

Kaine Seeks Senate Vote on War Powers Resolution

Kaine said his war powers resolution would require the administration to obtain congressional authorization before conducting further military action against Iran. He expects the vote as early as Tuesday.

“This is a president who ran on ending wars and yet has used the military without congressional authorization in multiple locations,” Kaine told reporters, pointing to recent operations in Iran and elsewhere.

Even if the resolution fails in the Republican-controlled Congress, Kaine said it could still pressure the White House to provide more transparency.

He cited a similar effort earlier this year related to Venezuela, which did not pass but coincided with the administration scaling back its military plans and agreeing to hold public hearings.

A companion measure has been introduced in the House by Reps. Ro Khanna, D-Calif., and Thomas Massie, R-Ky., highlighting rare bipartisan concern over presidential war authority.

Massie said lawmakers should be required to go on record.

“The Constitution requires a vote, and your Representative needs to be on record as opposing or supporting this war,” he wrote on social media.

Congress Divided as Briefings Expected

Lawmakers are sharply split along party lines.

Many Republicans have backed the strikes, framing them as necessary for national security. Most Democrats have criticized the operation as unlawful without congressional approval.

Still, some Republicans — including Massie, Rep. Warren Davidson of Ohio, and Sen. Rand Paul of Kentucky — have raised constitutional concerns.

Meanwhile, Sen. John Fetterman, D-Pa., broke with many in his party by supporting the strikes.

Kaine said lawmakers are expected to receive classified briefings soon but expressed frustration with the lack of public information.

“The administration comes in with briefers, takes most of the time presenting, and only a handful of senators get their questions answered,” he said.

First U.S. Casualties Reported in Iran Conflict

The Pentagon confirmed Sunday that three U.S. service members were killed and five seriously wounded in connection with the operation. Reports indicate the troops were stationed in Kuwait.

In a video statement, Trump acknowledged the losses and warned Americans to expect more casualties.

“We pray for the full recovery of the wounded and send our immense love and eternal gratitude to the families of the fallen,” Trump said. “And sadly, there will likely be more before it ends.”

He added that the United States would retaliate forcefully.

Earlier, Trump told a British newspaper the conflict could last up to four weeks.

Limited Public Explanation From White House

Nearly two days after the operation began, the administration has provided limited public justification.

The White House, Pentagon, and State Department have not held formal press briefings, a contrast to previous military operations when officials typically addressed reporters quickly to explain the rationale and objectives.

Instead, most operational details have come from U.S. Central Command’s social media updates.

According to CENTCOM, U.S. forces used B-2 stealth bombers, F-35 fighter jets, and a new one-way attack drone known as LUCAS. Missile defense systems including Patriot and THAAD batteries were also deployed.

Targets reportedly included Iranian command centers, ballistic missile sites, and naval vessels.

Trump claimed nine Iranian ships were sunk, though independent confirmation has not been released.

Experts Warn Conflict Could Expand

Military analysts say the scale of the operation suggests broader goals beyond Iran’s military infrastructure.

Mick Mulroy, a former Pentagon official, said the strikes appeared designed to threaten the Iranian regime itself.

“This is likely going to continue for weeks if not longer,” he said. “The region is now engulfed in a war.”

The conflict began with a massive joint U.S. and Israeli strike that killed Iran’s supreme leader, Ayatollah Ali Khamenei, prompting retaliatory missile attacks from Tehran.

Constitutional Clash and Uncertain Path Ahead

The unfolding confrontation has reopened a long-standing debate over presidential war powers and Congress’ authority under the Constitution.

While Kaine’s resolution faces long odds, it could force lawmakers to publicly take sides on one of the most consequential military decisions in recent U.S. history.

With American casualties mounting and no clear timeline for victory, pressure is likely to grow on the White House to explain its strategy — and on Congress to decide whether to formally authorize the war.
