The newest version of the health care bill doesn't have enough support to be considered on the Senate floor.
On Monday night, Republican Sens. Jerry Moran and Mike Lee announced they won't support the bill in its current form.
The two join their Republican colleagues Sen. Susan Collins and Sen. Rand Paul in planning to oppose a motion to proceed to consider the bill.
