The U.S. Department of Justice’s Office of the Inspector General (OIG)released a 500-page report Thursday detailing the results of a long-running inquiry into whether the Federal Bureau of Investigation (FBI) led by James Comey acted inappropriately leading up to the 2016 election with its handling of the Hillary Clinton email investigation.
