- The U.S. Senate voted 50-48 to approve a war powers resolution blocking U.S. military action against Iran, marking the first time the chamber passed such a measure after 10 previous attempts.
- Four Republican senators — Lisa Murkowski, Susan Collins, Rand Paul, and Bill Cassidy — joined Democrats; Democrat John Fetterman of Pennsylvania was the lone dissenter on his side.
- The Iran deal includes a US$300-billion fund to help Iran rebuild, dwarfing the US$1.7-billion Barack Obama's administration returned to Iran under the 2015 nuclear deal, drawing sharp GOP criticism from Ted Cruz and others.
- Trump signed a Memorandum of Understanding with Iran last week starting a 60-day clock for a broader agreement on Iran's nuclear program, while Vice President JD Vance works overseas to negotiate Tehran's nuclear rollback.
- The Pentagon is seeking roughly US$80-billion in supplemental funding to backfill munitions and stockpiles, part of a broader US$1.5-trillion annual defense ask — a nearly 50% increase — that Democrats branded 'Operation Epic Failure.'
- The GOP majority was eroded by the absences of Mitch McConnell, hospitalized for an undisclosed matter, and Dave McCormick, whose missing votes let the symbolic resolution pass without a presidential signature.
Why it matters: Four Republican senators broke with Trump on Iran, delivering the Senate's first-ever war powers passage against the war (50-48) — a symbolic but politically devastating rebuke. The financial stakes are staggering: a US$80-billion Pentagon supplemental and a US$1.5-trillion annual defense ask land alongside GOP alarm over a US$300-billion Iran reconstruction fund that towers over Obama's US$1.7-billion 2015 deal.
