The Senate passed the "Big, Beautiful Bill" by a single vote. However, before it can make its way to Trump's desk and officially into law, the bill will go back to the U.S. House of Representatives, which will look through and attempt to approve the Senate's changes.

Lawmakers voted largely along party lines to advance the megabill, overcoming weeks of closed-door negotiations and internal disagreements.

After a late shift by Senator Lisa Murkowski to yes, the legislation now returns to the House, where its passage remains far from certain.
