The United States Senate has approved a congressional measure calling on President Donald Trump to cease military operations against Iran unless lawmakers formally authorise further involvement.
The proposal cleared the Senate on Tuesday in a 50-48 vote, with several Republicans breaking ranks to support Democrats.
Although the action reflects congressional opinion, it carries no legal authority and will not be forwarded to the president for approval.
The decision follows growing concern among legislators over the prolonged conflict, which is nearing its fifth month despite a ceasefire arrangement reached earlier this year.
Some members of President Trump’s own party have questioned the administration’s handling of negotiations with Tehran and expressed doubts about the peace framework currently in place.
President Trump dismissed the Senate action, describing it as ineffective and poorly timed.
In a post on Truth Social, he argued that lawmakers had complicated efforts to secure a favourable outcome with Iran but insisted his administration would continue pursuing its objectives.
The vote is historically significant, marking the first occasion since the 1973 War Powers Resolution that both chambers of Congress have endorsed a concurrent resolution directing a president to terminate an overseas military campaign.
Unlike legislation that becomes law after presidential approval, a concurrent resolution serves as a formal expression of congressional opinion.
Political analysts noted that the measure lacks binding authority but demonstrates increasing public dissatisfaction with the conflict.
Middle East expert Laura Blumenfeld described the action as a symbolic reprimand rather than a meaningful restriction on presidential powers.
However, she said it reflects growing frustration among Americans, particularly as rising fuel costs have affected households nationwide.
The House of Representatives approved the same proposal earlier this month by a narrow margin of 215-208, with four Republicans joining Democrats in support.
The White House maintained that the resolution has little practical relevance because a ceasefire agreed on 7 April effectively ended active hostilities.
Administration officials also pointed out that two Republican senators, Mitch McConnell and Dave McCormick, were absent during the vote.
Republican senators Rand Paul, Lisa Murkowski, Susan Collins and Bill Cassidy sided with Democrats in favour of the measure, while Democratic Senator John Fetterman was the lone member of his party to oppose it.
The outcome highlights continuing divisions within Republican ranks ahead of November’s midterm elections, when control of Congress will be contested.
Recent disagreements have also emerged over defence spending, foreign assistance and other key administration priorities.
Tuesday’s ballot marked the tenth war-powers challenge initiated by Senate Democrats since fighting began.
It coincided with a Pentagon request for approximately $80 billion in funding, much of it intended to cover military expenditures linked to the Iran campaign.
Under US law, military engagements lasting beyond 60 days generally require congressional authorisation.
While operations against Iran commenced on 28 February, the administration contends that April’s truce effectively restarted the legal timetable. The executive branch also retains authority to extend military action for an additional 30 days on national security grounds.
Washington and Tehran are currently observing a ceasefire while pursuing negotiations under a memorandum of understanding signed by both governments last week.
The agreement provides a 60-day window for discussions aimed at reaching a broader settlement concerning Iran’s nuclear activities and a permanent end to the confrontation.
