Senate Majority Leader Mitch McConnell (R-Ky.) will ask the Senate as early as Tuesday to begin debate on a bill to gut the Affordable Care Act, but not even Senate Republicans know what bill they will be asked to vote on. It isn't entirely clear they will know before voting to open debate, either. Some senators said that McConnell has assured them they would be told before voting on the "motion to proceed" whether they would be proceeding to a vote on one of the versions of a bill to repeal and replace ObamaCare or just to repeal much of the law. The No. 2 Senate Republican, Sen. John Cornyn (R-Texas), said late last week that letting senators know what bill they would be voting on is "a luxury we don't have."

McConnell's current strategy "is to lean heavily on lawmakers to at least vote to allow debate on the bill, in the hopes that amendments and other tweaks could yield an agreement," The Wall Street Journal reported Sunday. That strategy carries some risk, as do all the others. McConnell put together his version of the bill with no public hearings or deliberation in committee. On Friday, the Senate parliamentarian issued a preliminary ruling that some two dozen provisions in the GOP bill would require 60, not 50, votes, throwing a new wrinkle in McConnell's plans to pass the bill using the budget reconciliation process.

On Saturday, President Trump urged Senate Republicans to "step up to the plate" and "vote to repeal and replace" ObamaCare.
