Former FBI Director James Comey “deviated” from official procedures in how he handled the agency’s investigation into Hillary Clinton, and consequentially hurt the organization’s reputation, the Justice Department inspector general concluded in its report to be released Thursday.

“While we did not find that these decisions were the result of political bias on Comey’s part, we nevertheless concluded that by departing so clearly and dramatically from FBI and department norms, the decisions negatively impacted the perception of the FBI and the department as fair administrators of justice,” Inspector General Michael Horowitz wrote, according to Bloomberg, which obtained the conclusions of the report hours before it is set to go public.
