Senate Republicans narrowly passed President Trump’s sweeping tax cuts and spending reduction bill on Tuesday, overcoming stiff resistance from Democrats and even dissent within their own party after a volatile overnight session.

Vice President JD Vance cast the tie-breaking vote in the evenly split 50-50 chamber, securing the bill’s passage.

The measure now returns to the House, where Speaker Mike Johnson had warned the Senate not to stray far from what his chamber had already passed. However, senators made several adjustments—especially concerning Medicaid—which could complicate final negotiations as lawmakers race to meet Trump’s July Fourth deadline.

The vote capped a tense weekend on Capitol Hill, with the president’s top legislative priority teetering between success and collapse. Despite holding the majority in Congress, Republicans struggled to shepherd the bill through the Senate, and their challenges aren’t over.
