retired. The report included an appendix disputing claims in the Fortune article. Following its publication, Dodson's lawyer wrote the managing editor of Fortune stating the article was "demonstrably false" and that a retraction was in order. After Fortune did not retract the article, Dodson sued for libel on October 12, 2012. On September 19, 2012, the Department of Justice Inspector General Michael Horowitz publicly released a 471-page report detailing the results of the Justice Department's own internal investigations. The Inspector General's report, which had access to evidence and interviews with witnesses not permitted in previous Congressional reports, recommended 14 federal officials for disciplinary action, ranging from ATF agents to federal prosecutors involved in the Fast and Furious operation.

The 14 Justice Department employees were referred for possible internal discipline. The Justice Department's Criminal Division head Lanny Breuer, an Obama administration presidential appointee, was cited for not alerting his bosses in 2010 to the flaws of Operation Wide Receiver.
