The Justice Department’s Office of Inspector General has issued this report. A snippet:

Although some of these media contacts were authorized under the FBI’s media policy, particularly those contacts by individuals working in the FBI’s OPA, many of the others were not. Most of the FBI employees interviewed by the OIG acknowledged their media contacts but denied sharing any non-public law enforcement information during those contacts. Employees interviewed by the OIG generally claimed that they believed their contacts were either authorized by OPA or a field office Special Agent in Charge (SAC) or Assistant Director in Charge (ADIC) to provide background about an FBI initiative or completed investigation, or were personal in nature. Given the absence, in most instances, of any documentary evidence reflecting the substance of these communications, the OIG was unable to determine whether these communications were consistent with the explanations provided by the FBI employees or instead involved the sharing of non-public information with reporters. The OIG received various investigative leads about specific individuals, which helped narrow the focus of the investigation from the dozens of FBI employees who had contact with the reporters. However, the number of employees in communication with these reporters still remained substantial, making it exceedingly difficult, absent an admission, to determine whether any of these FBI employees had in fact disclosed non-public information. Thus, these leads did not ultimately result in the identification of the source(s) of the alleged unauthorized disclosures of non-public information described in the 2016 pre-election report. Accordingly, with the issuance of this report and the July 20, 2021 summary of misconduct findings, the OIG has completed its investigations related to the improper disclosures of non-public information described in the 2016 pre-election report.
