(Bloomberg) — President Donald Trump lashed out at John Brennan in the latest effort to counter criticism of his decision to revoke the former U.S. spy-in-chief’s security clearance. Trump said in a tweet early Saturday that Brennan “will go down as easily the WORST” CIA director in history and called him “a loudmouth, partisan, political hack who cannot be trusted with the secrets to our country!” Has anyone looked at the mistakes that John Brennan made while serving as CIA Director?
