The last-ditch effort came after senators voted 55-45 against a straight repeal of Obamacare, with a two-year delay for Congress to work out a replacement.
The Senate deadlocked 50-50 on moving forward with the healthcare debate, forcing vice president Mike Pence to cast the tie-breaking vote.
The Bill played to the party’s disparate factions by letting insurers sell cheap, bare-bones policies while retaining taxes on the wealthy.
Senate Majority Leader Mitch McConnell abandoned plans to seek passage of it this week because Republicans did not have the requisite 50 votes to pass it.

A White House official said Trump and Pence were “open to constructive improvements that maintain the core principles and get the Bill over the goal.”
In a battle waged since the 2010 passage of the Affordable Care Act, Republicans including President Donald Trump had vowed to replace the law.
