After a dramatic procedural vote late Saturday night and a nearly 16-hour reading of the bill, the Senate started debate on Trump’s megabill.

Congressional Republicans are hoping to send their sweeping tax and spending cuts package, otherwise known as the “big, beautiful bill,” to President Donald Trump’s desk by July 4. The House and Senate have each narrowly passed their own versions of the bill.

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