DO OR DIE: Republicans have just hours left before the final vote on their massive tax bill

• The Senate is aiming for a final vote on the gigantic Republican tax bill on Friday afternoon.
• While Republicans are still arguing over details, it appears they have enough votes.
• The bill would make huge changes to business and individual taxes.

The final vote on the massive Senate Republican tax bill is fast approaching on Friday as GOP leaders scrambled to make last-minute changes to their bill.

A vote on Friday would come just three weeks after the bill, the Tax Cuts and Jobs Act (TCJA), was introduced.

Republicans appear to have the votes to pass the TCJA, but the situation is still fluid. Sen. John Cornyn, the second-ranking Senate Republican, said Friday morning that Republicans had enough votes to pass it. Sen. Bob Corker, a Republican holdout on the TCJA, said the bill would likely get through with or without his vote.

"I realize that there's probably enough votes right now to pass it," Corker told reporters.

Senate Majority Leader Mitch McConnell is attempting to appease deficit hawks, moderates, and members concerned about small business all while keeping the TCJA within Senate rules.
