The US Senate on Tuesday (May 19) approved a resolution aimed at limiting President Donald Trump’s authority to engage in military action against Iran, marking a rare legislative victory for Democrats after several unsuccessful attempts.

The measure advanced out of committee with a 50-47 vote, supported by four Republican senators; Susan Collins of Maine, Lisa Murkowski of Alaska, Rand Paul of Kentucky, and Bill Cassidy of Louisiana, who joined most Democrats in backing the proposal. Pennsylvania Senator John Fetterman was the only Democrat to oppose the resolution.

The vote represented the first time a Senate war powers resolution related to Iran had gained sufficient support to move forward. Three Republican senators abstained, helping shift the balance in favor of the measure.

Although the resolution still faces additional hurdles in Congress and is expected to encounter a presidential veto if passed by both chambers, Democratic lawmakers said the vote sends a strong signal about congressional oversight of military action and presidential war powers.

The development comes amid ongoing tensions stemming from the conflict involving the United States, Israel, and Iran, which began in late February. The hostilities triggered retaliatory strikes across the region and disrupted shipping through the Strait of Hormuz, a critical route for global energy supplies.

Diplomatic efforts between Washington and Tehran later produced a temporary ceasefire and negotiations in Islamabad in April. However, talks stalled over disagreements surrounding Iran’s nuclear activities and access to the Strait of Hormuz.

Following the deadlock, the Trump administration ordered a naval blockade targeting Iranian ports in an effort to increase economic pressure on Tehran. Although Iran briefly reopened the Strait of Hormuz after a separate ceasefire agreement involving Israel and Lebanon, shipping access was later restricted again as tensions over the blockade persisted.

The Senate vote highlights growing debate in Washington over the scope of presidential military authority as the conflict with Iran continues to shape US foreign policy and regional security dynamics.
