Former FBI Director James Comey admitted he was wrong to defend the FBI’s use of the Foreign Intelligence Surveillance Act process after he previously claimed vindication following the release of Department of Justice Inspector General Michael Horowitz’s report on his investigation into the origins of the 2016 Russia investigation.

Earlier this week, Horowitz released his report, which found that no political bias led to the opening of the investigation into alleged collusion between President Trump’s 2016 campaign and Russia. He did, however, find 17 “significant errors or omissions” by FBI officials in obtaining FISA warrants to monitor onetime Trump campaign adviser Carter Page.
