FBI agent John Robertson (left) found the messages that led to the Hillary Clinton email investigation being reopened days before the 2016 election. He said the way the bureau handled the case was 'not ethically or morally right'. Robertson feared he would be made a 'scapegoat' when he found the emails in the wake of DailyMai.com's revelation that Anthony Weiner (right) was sexting a minor. The disgraced congressman's wife Huma Abedin was Clinton's top aide (inset top center). Robertson said the FBI did nothing for a month until he went outside the chain of command and spoke with the US Attorney's office overseeing the case. The only advice from his bosses was to erase his office computer, which meant leaving no record of his investigations, a new book October Surprise: How the FBI Tried to Save Itself and Crashed an Election says. Robertson's claims add another layer of intrigue to the investigation of Clinton's emails which has become one of the most divisive episodes of the 2016 election.
