The Department of Justice's Office of the Inspector General has dropped a 500-page report detailing its investigation into the conduct of FBI personnel, including former FBI Director James Comey, during the investigation into former Secretary of State Hillary Clinton's use of a private email server (code-named "Midyear Exam") and related events just before the 2016 presidential election. The report reveals details of the FBI's internal communications, including an apparent agency-wide distaste for Lync, the mandated official messaging application for the FBI's internal networks.

Sure to be a hot summer read for some in Washington, DC, the review does not find fault with the Justice Department's decision not to pursue prosecution of Clinton or members of her staff, and it finds no evidence of political bias. But it does call out Comey and others for violations of policy and calls Comey's decision to independently announce the results of the Clinton investigation as insubordination.
