I can't speak for Comey but he spoke for himself and said that he had to choose between disclosure and concealment and he thinks he made he right call given the information at hand. Hillary chose to set up a private server and compromised national security in doing so period. She can blame Russia, Comey, Bernie, Sexism, racism, the Easter bunny, or whomever else she'd like. I enjoyed her last 100 days as not president.
