US Senate advances resolution to curb Trump's power to wage war on Iran
The US Senate has advanced a 'war powers' resolution aimed at limiting President Donald Trump's authority to take military action against Iran. The measure must still clear additional votes to become law.

The US Senate has advanced in a procedural vote a resolution making any military action against Iran subject to Congressional approval. The threshold was cleared with support from Democrats and a group of Republicans, reviving the legislative-balance debate amid heightened Iran tensions in recent weeks.
The resolution invokes the 1973 War Powers Resolution to limit the president's ability to launch new military operations without Congress. To become law it needs a final Senate vote and approval from the House of Representatives; if Trump vetoes, Congress would need a two-thirds majority to override.
The Trump administration argues the resolution intrudes on the president's constitutional authority. Tehran, in recent statements, has framed itself as 'open to negotiation' while continuing to signal military readiness.
