A resolution aimed at limiting President Donald Trump’s authority to wage war in Iran failed in the U.S. Senate for the fourth time. Lawmakers rejected the measure in a 52-47 vote, largely along party lines.
The proposal sought to require congressional approval before continuing U.S. military action in the conflict. If passed, it would have curtailed the president’s ability to proceed without authorization from Congress, the BBC reported.
Democrats said they intend to continue introducing similar resolutions on a weekly basis. They said the effort is designed to put lawmakers on record regarding their positions on the war.
Most Republicans have voted to block the measures so far. However, some have indicated their positions could shift if the conflict extends beyond the current timeline.
President Donald Trump has offered varying assessments of how long the conflict may last.
In an interview aired Wednesday, he said the war was “close to over.”
Republican lawmakers have largely maintained support for the president’s actions. That support has continued as the administration enforces a U.S. military blockade of Iranian ports.
One Democrat, John Fetterman, voted against the resolution. His vote aligned with Republicans in opposing the measure.
Republican Sen. Josh Hawley said he believes ending the conflict quickly would be in the country’s interest. He said in an interview he hoped negotiations could succeed in the coming days.
“That would be ideal,” Hawley said. He did not indicate how he would vote if the conflict continues beyond the current period.

Sen. Rand Paul was the only Republican to vote with Democrats in favor of the resolution.
It marked the fourth time he has taken that position on similar measures.
Federal law places limits on the duration of military actions without congressional approval. Under current statutes, authorization is required if hostilities extend beyond 60 days.
The current conflict timeline dates back to late February, when U.S. and Israeli strikes began. That timeframe has prompted renewed debate over the application of existing war powers laws.
Paul said additional Republicans could reconsider their positions if the timeline continues to extend. “I think that after 60 days, there may be a few more Republicans [who] join me,” he said.
Fetterman: “Every single thing Iran has done is a war crime.
We are the force of good in the world.Now, less than 40 days into this, they’re trying to force another War Powers vote — and I will vote against it.” pic.twitter.com/Xh46YYUvxv

The White House has the ability to extend the timeline under certain conditions. Officials can invoke national security provisions to allow for an additional 30-day period.
Democrats said they will continue pressing the issue despite repeated defeats. They said ongoing votes ensure public accountability for decisions related to the conflict.
“If we’re unsuccessful, at least we’ll make clear to the American people who owns this war,” said Sen. Tim Kaine. He has been among the leading proponents of the resolution.
The War Powers Resolution of 1973 governs the legal framework for congressional oversight of military action. It was enacted during the presidency of Richard Nixon to limit executive authority following the Vietnam War.
The law was designed to ensure that Congress plays a central role in decisions involving extended military engagement. Its provisions continue to shape debates over presidential war powers in current conflicts.
The Senate made headlines earlier this week when Republicans moved the SAVE America Act forward, setting up a renewed legislative fight this week over election rules as GOP leaders signal the bill will be a top priority in the coming weeks.
The Senate voted 51–48 to advance the legislation last week by approving a motion to proceed, clearing a key procedural hurdle and allowing formal debate to begin.
The measure now returns to the floor after previously stalling, with Sen. Mike Lee urging conservatives to maintain pressure on lawmakers to ensure final passage.
Supporters of the SAVE America Act say it is designed to strengthen confidence in federal elections by adding new requirements and oversight mechanisms.
The bill would require proof of U.S. citizenship when registering to vote in federal elections, tighten voter identification rules, and expand federal involvement in maintaining voter rolls.
Republican lawmakers argue these changes are necessary to ensure that only eligible citizens participate in elections and to address concerns about how voter registration systems are managed.
