The US Senate has rejected for the fourth time a resolution seeking to limit President Donald Trump’s authority to wage war with Iran. The measure, voted down 47–53 mostly along party lines, followed a two-week ceasefire between the US and Iran that began last week. Talks in Islamabad, Pakistan, failed to produce a lasting peace, though both sides indicated willingness for further dialogue. The resolution’s defeat came despite renewed calls from lawmakers to curb Trump’s unilateral military actions, which began alongside Israel on February 28.

Supporters argued that Trump acted outside constitutional authority, while opponents insisted he was within his presidential rights. Senator Chris Murphy criticized the conflict as mismanaged and costly, citing billions spent weekly and over a dozen American deaths. Republican Senator Jim Risch defended Trump’s actions as a duty to protect the US. The House of Representatives is expected to vote on a similar measure, though any passage would be largely symbolic given Trump’s veto power.

The ceasefire’s future remains uncertain as US forces maintain a naval blockade near Iran and both nations prepare for possible renewed talks in Islamabad.
