Republicans will likely be briefed on changes made to the GOP's healthcare bill during a closed-door lunch Tuesday.
The changes were made during July 4 recess.
The next step is for the Congressional Budget Office to score the new plan.
After the CBO scored the original GOP plan, 9 Republican Senators came out against the bill.
If all Democrats vote no, Republicans can only afford to lose two votes.
A vote is expected as early as next week.
