A fourth attempt to curb presidential war authority has failed in the United States Senate, underscoring deep political divisions over the ongoing conflict with Iran and raising fresh questions about constitutional limits on executive power.

Lawmakers voted 47–52 against a resolution aimed at restraining President Donald Trump from continuing military operations against Iran without explicit congressional approval. The measure saw rare cross-party defections, with Republican Rand Paul supporting the resolution and Democrat John Fetterman opposing it.

The vote came days after Washington and Tehran agreed to a fragile two-week ceasefire following weeks of escalating hostilities. Despite the temporary pause, diplomatic efforts in Islamabad failed to secure a lasting agreement, though both sides have indicated willingness to resume negotiations.

According to Al Jazeera, the failed resolution reflects a broader struggle within US politics over war accountability, with critics arguing that the administration bypassed constitutional checks by entering the conflict alongside Israel on February 28 without formal congressional authorization.

Supporters of the resolution argue that the US Constitution grants Congress not the president, the authority to declare war, except in cases of immediate self-defense. They accuse the Trump administration of stretching that justification, citing Iran’s actions since the 1979 Islamic Revolution as a basis for “imminent threat.”

Speaking ahead of the vote, Democratic Senator Chris Murphy sharply criticized the war, calling it a “bungled, mismanaged” campaign that has drained billions of dollars and destabilized the broader Middle East. He also condemned what he described as a lack of transparency and oversight from Republican leadership.

Republican Senator Jim Risch defended the president’s actions, arguing that Trump not only has the authority but also the obligation to act in defense of American citizens, dismissing the resolution as politically motivated.

The political battle is expected to continue in the House of Representatives, where a similar resolution is anticipated. While it may gain more traction there, any measure passed by Congress would likely face a presidential veto requiring a two-thirds majority in both chambers to override, a threshold widely seen as unattainable.

A more decisive moment looms at the end of April, when the conflict reaches the 60-day limit set by the War Powers Act of 1973. Without congressional authorization or an approved extension, the law would compel the administration to begin withdrawing US forces setting the stage for a critical constitutional and political showdown in Washington.
