Senate GOP blocks war powers resolution as US-Iran conflict hits 200 days

Senate Republicans voted 49-50 to block a House-passed war powers resolution aimed at ending US military involvement in Iran, as the conflict surpasses 200 days with 19 US service members killed. The vote underscores congressional-executive tension over war authority, but the resolution's failure means no immediate change in US force posture. The ongoing conflict and mounting casualties raise domestic political stakes ahead of elections.
