The Justice Department’s top watchdog said, in a scathing report released Thursday, that former FBI Director James Comey was “insubordinate” during the 2016 presidential campaign, when he took unilateral actions that could have impacted the outcome of the vote. Inspector General Michael Horowitz said in the 500-page report that Comey mishandled the investigation into Hillary Clinton’s emails, making a “serious error in judgment” by telling Congress on the eve of the election that he was reopening an investigation into whether Clinton illegally circulated classified information on a private email server. Even so, the report did not conclude that Comey held a bias that influenced his decisions. The inspector general also found at least five FBI officials assigned to the Clinton investigation improperly made anti-Trump or pro-Clinton statements over text messages or by other means. This is FBI Director Christopher Wray, speaking Thursday after the report’s release.

Christopher Wray: “This report did not find any evidence of political bias or improper considerations actually impacting the investigation under review. The report does identify errors of judgment; violations of, or even disregard for, policy; and decisions that, at the very least, with the benefit of hindsight, were not the best choices. We’ve already started taking the necessary steps to address those issues.”

President Trump immediately seized on the report to justify his decision to fire Comey just six months after Election Day. Trump tweeted, “Comey will now officially go down as the worst leader, by far, in the history of the FBI. I did a great service to the people in firing him. Good Instincts.”
