Senator John McCain (R., Arizona), recently diagnosed with brain cancer, has confirmed that he will return to the Senate this afternoon to vote on bringing health care reform to the floor for debate. Specifically, Senate Majority Leader Mitch McConnell (R., Kentucky) is expected to ask for  a procedural vote to approve debate on the Senate’s version of the “repeal and replace” and/or “repeal” bill regarding the Affordable Care Act (ACA). This vote is needed to continue the Republicans’ 7- year promise to repeal and replace the ACA.
