The Republican tax plan could slam into a wall tomorrow
- The Senate Budget Committee is scheduled to take up the GOP tax bill on Tuesday.
- GOP Sen. Ron Johnson said that without changes he will not vote for the bill in committee.
- Since Republicans only have a one-vote majority in the Committee, Johnson's defection would prevent the bill from making it to the Senate floor.
Senate Republican leaders have little time in which to come up with a change to their tax bill, or the measure could stumble on a key procedural hurdle.
