- The Senate will vote Tuesday on its 10th war powers resolution to block U.S. military action against Iran, a series that has failed every time as Republicans hold the narrow majority and one Democrat (John Fetterman) has typically voted against.
- A growing bloc of Republicans in both chambers has broken with the administration over the war and Trump's deal with Iran — Sen. Ted Cruz said on his podcast that Trump is "getting very poor advice on Iran," and Trump is personally heading to the Capitol to pressure holdouts.
- The Iran deal is governed by a Memorandum of Understanding Trump signed last week starting a 60-day clock for a broader nuclear agreement, and includes a $300 billion fund to help Iran rebuild — a figure Republicans have flagged as far exceeding the $1.7 billion Obama returned under the 2015 deal.
- The House passed its own war powers resolution earlier this month with four Republicans joining all Democrats, and the Senate will now consider that House-passed version, which carries no force of law but would amount to a symbolic rebuke.
- Defense Secretary Pete Hegseth is on Capitol Hill this week seeking roughly $80 billion in supplemental funding to backfill munitions and stockpiles, with the Pentagon's own early estimate of $11.3 billion for the war's first week and outside experts putting the total near $100 billion.
- The Trump administration is separately seeking $1.5 trillion in defense funding this year — a 50% increase — including $350 billion in a budget reconciliation package GOP leaders are pushing through over Democratic objections.
Why it matters: GOP dissent over Trump's $300 billion Iran deal and an $80 billion supplemental war-funding request puts the Senate's 10th war powers vote within reach of its first majority. Breaking ranks costs the administration its congressional shield for a war launched without authorization — right when it needs Congress to fund the $80 billion backfill.
