Senate advances measure to end military action in Iran in rebuke to Trump
Overview
The Senate on Tuesday voted 50-47 to advance a War Powers Resolution that would restrict President Donald Trump's ability to conduct military action against Iran.
The procedural vote came after growing concern about a war with Iran that has passed the 60-day mark under the War Powers Act and amid a fragile ceasefire.
Sen. Bill Cassidy, R-La., who lost his primary to Rep. Julia Letlow after Trump's endorsement, said the White House and Pentagon have left Congress in the dark on "Operation Epic Fury."
The 50-47 vote included GOP defections from Rand Paul, Susan Collins, Lisa Murkowski and Bill Cassidy, while Sens. Thom Tillis, John Cornyn and Tommy Tuberville did not vote.
The resolution still needs a final Senate vote, House approval and would likely face a presidential veto, and the House is expected to vote on a similar measure Wednesday.
Analysis
Center-leaning sources frame this as a political rebuke to Trump, using loaded language ("political blow," "bad omen," "simmering tensions") and emphasizing Republican defections and electoral pressures. Editorial choices highlight GOP infighting and cite Democratic and anti‑Trump GOP voices; direct quotes (e.g., Kaine, Murkowski) are presented as source content.
