Congress passes war powers measure for first time, breaking with Trump over Iran

June 24, 2026

The Republican-controlled Senate voted 50-48 to approve a concurrent resolution demanding President Trump either end military operations in Iran or obtain congressional authorization to continue, marking the first time both chambers have passed such a measure since 1973. Though the resolution passed both the House and Senate, it carries no legal weight and won't be sent to Trump for signature, making it primarily symbolic. The vote reflects growing Republican divisions and public discontent over the unpopular conflict, now in its fifth month, which has caused fuel prices to surge.

Who is affected

President Donald Trump and the White House administration
Republican members of Congress (particularly the four senators who broke ranks: Rand Paul, Lisa Murkowski, Susan Collins, and Bill Cassidy)
Democratic members of Congress
The American public (experiencing high petrol prices)
US and Iranian military forces currently under ceasefire
Sailors stranded in the Strait of Hormuz

What action is being taken

The US Senate is voting on war powers resolutions (this was the 10th such vote)
The Pentagon is requesting $80 billion from Congress, primarily for the Iran war
The US and Iran are working to negotiate a broader agreement on ending Iran's nuclear program under the 60-day memorandum of understanding
Ships are moving through the Strait of Hormuz following the US-Iran deal

Why it matters

This represents the first time since 1973 that both congressional chambers have approved a resolution instructing a president to end military action, signaling significant bipartisan opposition to the Iran conflict. While legally non-binding, the measure reflects widespread public discontent with the unpopular war and adds political pressure on the White House to find a resolution. The vote also highlights deepening divisions within the Republican Party ahead of midterm elections that will determine whether they maintain control of Congress, potentially weakening Trump's political position and ability to conduct foreign policy without legislative pushback.

What's next

Washington and Tehran have 60 days (from the signing of the memorandum) to negotiate a broader agreement on ending Iran's nuclear program
Midterm elections will be held in November, determining whether Republicans retain congressional majorities
The US and Iran are continuing their ceasefire and working towards ending hostilities under the memorandum of understanding
