Republican Sen. Ron Johnson seemingly suggested last week that Sen. John McCains brain tumor may have affected the Arizona Republicans judgment when he voted against the skinny repeal of Obamacare late last month. CNN on Wednesday unearthed audio from a Chicago radio show last week, in which Johnson said of the shocking moment McCain voted against the proposal: Im not gonna speak for John McCainhe has a brain tumor right now, that vote occurred at 1:30 in the morningsome of that might have factored in. A seemingly shocked radio host replied, Really? and asked if the senator truly believed McCains decision-making was clouded by his tumor. Again, I-I-I dont know exactly what we really thought and again I dont want speak for any senator, the Wisconsin Republican stammered. I really thought he was going to vote yes to send that to conference at 10:30 at night. By about 1, 1:30, he voted no. So you have talk to John in terms what was on his mind. McCains office responded to Johnsons comments in a statement later Wednesday. It is bizarre and deeply unfortunate that Senator Johnson would question the judgment of a colleague and friend. Senator McCain has been very open and clear about his reasons for the vote, spokeswoman Julie Tarallo said. Johnson later backtracked, writing in a statement: Im disappointed I didnt more eloquently express my sympathy for what Sen. McCain is going through. I have nothing but respect for him and the vote came at the end of a long day for everyone.
