Opinion: CNN’s shameful treatment of Bernie Sanders: Tribune columnist John Kass says the nation witnessed some bad journalism at Tuesday night’s presidential debate. Sanders was asked about a report he told fellow candidate Massachusetts Sen. Elizabeth Warren that a woman couldn’t be elected president. While he denied he ever said it, the reporter-moderator turned to Warren, who was also on the debate stage, and asked: "Sen. Warren, what did you think when Sen. Sanders told you a woman could not win the election?” Kass’s take is that the question ignored Sanders’ denial and treated the comment as fact.
