The Senate voted 52-48 on party lines to begin debate on the Republican tax bill, putting the Senate within striking distance of passing it. Several Republicans who have not committed to voting for the final bill, including Sens. Collins, McCain, Corker and Flake, voted in favor of moving ahead.

What's next: Republican leadership wants to pass the bill by the end of the week. There will be up to 20 hours of debate and votes on a series of amendments prior to the final vote. The House has already passed a different tax bill and, should the Senate pass its bill, they will have to agree on a compromise package.
