Former FBI Director James Comey “deviated” from FBI and Justice Department procedures in handling the probe into Hillary Clinton, damaging the law enforcement agencies’ image of impartiality even though he wasn’t motivated by political bias, the department’s watchdog found in a highly anticipated report.

“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 said in the report’s conclusions, which were obtained Thursday by Bloomberg News.
