The lunch, according to an aide, was expected to be at effort to both rally the troops and serve as a policy discussion. For McConnell's part, according to the aide, the message would be clear: A vote against the bill would be a vote to maintain Obamacare. If the bill failed, McConnell was set to argue, the only option would be to work with Democrats, which would lead to a less conservative outcome.
Pence expressed uncertainty earlier Tuesday on whether the bill would make it to the floor. "We'll see," he told CNN as he entered a meeting in the Capitol.
Pressed on what they are doing to salvage the bill, Pence responded, "lots of good discussions underway and we'll continue to work very diligently."
Also at the Capitol Tuesday was Florida Gov. Rick Scott, who was scheduled to hold meetings with Pence, McConnell and Sen. Marco Rubio, R-Florida.
Rubio, like some senators, had been waiting to make his decision on the bill until he felt like he had enough input from his state's governor and other constituents. An aide to the senator said Rubio's staff invited staff from the offices of Scott -- as well as the Florida speaker and Senate president -- to Washington to be "embedded" in Rubio's office for the week and work with Rubio's team to analyze how the bill will affect Florida.
Over on the House side, Speaker Paul Ryan urged his members in a closed door session to give their Senate colleagues some space, according to a person in the room.
Ryan's point was that given the current state of play, it's not helpful for anyone in the House to come out and attack or criticize elements of the bill. Should the Senate pass the bill, Ryan argued, the House will get their chance, one way or another, to weigh in. Until then, he urged members to hold their fire.
