Not that Burr is anything to write home about, but I think this is most likely misinformation from a confused staffer.
The staffer was very specific and said that Burr was going to vote yes on cloture, that S. 1776 had nothing to do with Obamacare, and then pointedly said that Docs needed to get paid for providing care to Medicare patients.
The staffer appeared to be well-informed re Burr’s intentions and the reason why Burr was voting for cloture and presumably for the bill.
We need to flood Burr’s offices with calls!!!
