Senate Democrats block $1.15 trillion defense bill over Iran war objections

Jul 13, 2026

Senate Democrats blocked a $1.15 trillion defense bill, citing President Trump's unauthorized war with Iran and the budget's size. The procedural vote failed 50-46, short of the 60 needed. The move comes as the Trump administration renewed military action against Iran, including a naval blockade, after a ceasefire collapsed. Democrats also object to the total $1.5 trillion defense spending request amid cuts to social programs.
