Senate Republicans on Thursday blocked a Democratic-backed war powers resolution aimed at limiting President Trump's military actions against Iran, the latest in a series of forced votes on the issue. Democrats have continued to call votes on the measure even after winning approval of a separate resolution calling on Trump to end the war, seeking to compel Republicans to publicly take a stance on presidential war authority. The latest resolution failed to advance, with Republicans standing by Trump. Sen. Bill Cassidy (R-La.) drew a hard line on deploying ground troops in Iran, signaling support for limited military engagement while opposing a broader ground war. The vote came as U.S. munitions stockpiles dwindle, amid ongoing tensions with Iran. Democrats argue that Congress must reassert its constitutional power to declare war, while Republicans maintain that Trump acted within his authority as commander in chief. The repeated votes are part of a broader effort to force a debate on the scope of presidential war powers, with Democrats using procedural tactics to put Republicans on the record. The outcome underscores the partisan divide on the issue, with no immediate prospect of compromise.
