The Justice Department's Inspector General, Michael Horowitz, will soon release a much-anticipated assessment of Democratic and Republican charges that officials at the FBI interfered in the 2016 presidential campaign. That year-long probe ... is expected to come down particularly hard on former FBI director James Comey. An earlier [report] in April by Horowitz ... showed that the ousted deputy director of the FBI, Andrew McCabe, had lied to the bureau's internal investigations branch to cover up a leak he orchestrated about Clinton's family foundation less than two weeks before the election. Another IG report in March found that FBI retaliation against internal whistle-blowers was continuing despite years of bureau pledges to fix the problem.

FBI agents are facing criminal charges ranging from obstruction to leaking classified material. And then there's ... the FBI's miss of the Russian influence operation against the 2016 election. Jeffrey Danik, a retired FBI agent ... blames the state of affairs on a severe lack of leadership" and transparency at headquarters.
