The US Senate passed a war powers resolution rebuking President Trump over Iran, then reversed course just one day later.
The dramatic back-and-forth highlighted deep divisions in Congress over the president’s authority to wage war.
It also revealed how quickly political pressure can reshape even a historic congressional vote.
The episode unfolded as sensitive US-Iran negotiations continued in the background this week.
Few votes in recent memory have swung so sharply in such a short span of time.
The Senate Passes the Iran War Powers Resolution

On June 23, the Senate voted 50 to 48 to limit President Trump’s ability to resume war with Iran.
Four Republicans joined Democrats to pass the measure in a rare rebuke of the president.
The crossover senators were Rand Paul, Susan Collins, Lisa Murkowski, and Bill Cassidy.
Democratic Senator John Fetterman broke ranks and voted against the resolution.
It marked the first time a war powers resolution had successfully passed both chambers of Congress.
As CNN report on the vote reported, the vote set up a potential clash with the White House.
Why the Resolution Was Largely Symbolic

Despite the historic vote, the resolution was always expected to be largely symbolic in practice.
It was not expected to become law, since the president can veto such measures.
The House had earlier passed its own version directing Trump to end hostilities with Iran.
Supporters argued the vote still sent a powerful message about congressional war powers.
Critics dismissed it as a gesture that would not change the administration’s actual policy.
The Washington Post coverage detailed how the measure aimed to curb the president’s military authority.
The Senate Walks Back Its Rebuke of Trump

Just one day later, the Senate reversed itself, rejecting an attempt to advance a similar measure.
Two Republicans who had backed the first resolution changed their positions on the second vote.
Senator Rand Paul voted present, while Senator Bill Cassidy voted against advancing the resolution.
The reversal handed the Trump administration a key procedural win on Iran policy.
Trump dismissed the earlier Senate rebuke as meaningless, lashing out at the vote publicly.
According to Time report on the reversal, the swift turnaround reflected intense political pressure behind the scenes.
