GOP Sen. Ron Johnson: McCain's brain tumor might have been factor in no vote on health care (CNN)

Republican Sen. Ron Johnson of Wisconsin said Tuesday that he thinks that Sen. John McCain's brain tumor and the early morning hours may have affected the Arizona Republican's no vote on the Senate bill to repeal Obamacare.

McCain voted no on the so-called skinny repeal, explaining in a radio interview last week that he disagreed with the process leading up to the vote and saying he supported repealing Obamacare but with an immediate replacement. McCain returned to the Senate to vote on health care-related legislation after a surgery to remove a blood clot revealed he had brain cancer.

Johnson argued that the brain tumor may have affected McCain's vote.
