Republicans have clinched the 50 votes need to pass their tax plan, after three key holdouts came on board.
The move puts the legislation on a path to clear the upper chamber as soon as Friday and puts Senate Republicans on the brink of a significant legislative and political victory.
Senate GOP leadership has been under a mountain of pressure to deliver on the tax bill after failing to repeal and replace ObamaCare in July and again in September.
Top Republican senators appeared confident on Friday that they had the votes, after GOP Sens. Steve Daines(R-Mont.) and Ron Johnson (R-Wis.) said they would support the plan.
