Senate Majority Leader Thune can bring the bill back for another vote using his procedural switch.
Senate Democrats blocked the National Defense Authorization Act (NDAA) on July 14, refusing to advance the $1.15 trillion annual defense bill in protest of President Trump’s war against Iran. The procedural vote failed 50-46, well short of the 60 votes needed. Democrats said Congress cannot approve Pentagon funding while the conflict drags into its fifth month without authorization or a clear exit strategy.
Why Democrats blocked the bill
Senate Minority Leader Chuck Schumer said the NDAA could not become a “permission slip” for Trump’s Iran operations. Democrats argued that Congress has voted more than 10 times on war powers resolutions to halt hostilities, but Republicans blocked all efforts. The White House formally notified Congress on July 13 that it had resumed bombing strikes against Iran, effectively ending a fragile ceasefire that had held for weeks.
What the bill would have funded
The NDAA would authorize $1.15 trillion in Pentagon spending and include a 3.6% pay raise for troops, investments in drone technology, and shipbuilding programs. Senate Majority Leader John Thune urged Democrats to support the measure, saying Congress has an obligation to provide military resources. The bill typically passes with broad bipartisan support and is considered must-pass legislation.
What happens next
Thune switched his vote to no after the bill failed, a procedural move that allows him to bring it back for another vote later. The House and Senate will negotiate a compromise version of the bill, which will then be sent to President Trump for approval or veto. It remains unclear how Democrats and Republicans will resolve their disagreement over Iran war guardrails before a final vote.
The Iran conflict’s toll
The war began in February without congressional authorization and has resulted in economic disruptions, including volatile gas prices. Trump had threatened to impose a 20% “security” fee on vessels transiting the Strait of Hormuz but backed down on July 14 while vowing to continue the U.S. blockade of Iranian ports. Some Democrats also objected to provisions in the bill that would deepen U.S. military and intelligence cooperation with Israel.
Final Thoughts
The NDAA blockade marks a rare setback for one of Congress’s most reliable pieces of legislation. Democrats have drawn a clear line: they will not fund Pentagon operations while Trump wages an unauthorized war without an exit plan or congressional buy-in.
