#13. John McCain
Who: Arizona Senator, 2008 Republican Presidential Nominee
What: McCain called Trump’s repeated praise of Russian President Vladimir Putin “incomprehensible” in December. According to a BuzzFeed story, during a radio interview, McCain said of Trump: “For him to provide propaganda, which is really what he just did for Vladimir Putin, who is a thug and a murderer, I think is really astonishing and shows either profound ignorance or an attitude that contradicts everything about the United States of America and our relations with our adversaries.”
