It’s only Horowitz’s extremely forgiving standard for judging investigative decisions that allows him to say that the impact of bias on the Clinton investigation is inconclusive. This is not to dismiss the usefulness of the IG’s report. It reaffirms that the president had ample legitimate grounds to dismiss Director Comey, who is shown to be insubordinate and deceptive, a self-absorbed law unto himself. Furthermore, the IG’s equivocation about the role of bias does not detract from his powerful condemnation of the disrepute rogue agents have brought on the bureau. Still, there is important work left to be done in fully accounting for the decisions of an FBI whose reputation won’t soon recover from its performance in 2016.
