Senate Republicans again block effort to halt Trump’s war in Iran

Senate Republicans have once again blocked a Democratic effort to halt President Trump's military actions in Iran. The Senate voted 47-50 against a war powers resolution that would have limited the conflict until Congress authorized further military action. This marks the sixth failed attempt by Democrats this year to limit the president's authority. The resolution's author, Senator Adam Schiff, highlighted its importance as Friday marks 60 days since the administration notified Congress of the strikes. Under the War Powers Resolution of 1973, military campaigns must end after 60 days without congressional authorization, though the Defense Secretary has stated the clock was paused due to a ceasefire. The House of Representatives also narrowly rejected a similar resolution earlier this month.

In April 2026, the US House of Representatives narrowly voted down a war powers resolution aimed at limiting President Trump's authority to wage war against Iran. The vote, 213-214, followed a similar failed attempt in the Senate along party lines. While most Democrats supported the resolution, only one Republican voted in favor, and one Democrat opposed it. The resolution sought to reassert Congress's constitutional power to declare war, following Trump's decision to initiate strikes against Iran in February, alongside Israel. Democrats argued that Republicans were enabling the President to act unilaterally in the ongoing conflict, which has resulted in casualties and economic consequences.

The US House of Representatives narrowly rejected a war powers resolution on Thursday that aimed to prevent further military action against Iran. The resolution, introduced by Democrat Greg Meeks, failed by a vote of 213-214, with Democrats largely uniting in opposition to continued US involvement. While most Democrats supported the measure, one voted against it, while one Republican voted for it and another voted present. Some Democrats who previously opposed similar resolutions shifted their position, citing dissatisfaction with the Trump administration's handling of the conflict and concerns about a costly, open-ended engagement. The vote occurred amidst ongoing peace talks between the US and Iran, with some arguing the resolution would weaken the US position during negotiations.
