summarizing the Midyear investigation, drafts of Comey's public statement and letters to Congress, and contemporaneous notes from agents and supervisors involved in meetings about the statement and letters to Congress. We also obtained documents from prosecutors and supervisors in the Department's National Security Division (NSD) and the U.S. Attorney's Office for the Eastern District of Virginia (EDVA), as well as the Office of the Deputy Attorney General (ODAG) and the Office of the Attorney General (OAG). Importantly, among these documents were contemporaneous notes from the prosecutors and supervisors involved in the investigation.
In connection with our efforts to investigate the circumstances surrounding the FBI's discovery of Midyear-related emails on Anthony Weiner's laptop computer and Comey's notification to Congress on October 28, 2016, we obtained documents from NYO and SDNY personnel. These documents included forensic logs from processing of the Weiner laptop by NYO Computer Analysis and Recovery Team (CART) personnel, NYO and SDNY communications about the discovery of the emails, and other documents.
We obtained communications between and among agents, prosecutors, supervisors, and FBI and Department officials to understand what happened during the investigation and identify the contemporaneous factors considered in making investigative decisions. In addition to a large volume of emails, we obtained and reviewed well in excess of 100,000 text messages and instant messages to or from FBI personnel who worked on the investigation.
Our review also included the examination of highly classified information. We were given broad access to relevant materials by the Department and the FBI, including the sensitive compartmented information (SCI) discussed in the classified appendix to this report and emails and instant messages from both the FBI's Top Secret SCINet system and Secret FBINet system. Several of the State Department emails between Secretary Clinton and her staff from the underlying Midyear investigation included information relevant to a tightly-held Special Access Program (SAP), and we did not seek or obtain the required read-ins for that program. Based on our review of emails containing redacted SAP and the FBI's explanation of the program, we determined that this information was not needed for us to make the findings in this report.
Finally, and as discussed in more detail below, our review included information obtained in the Midyear investigation and the Anthony Weiner child exploitation investigation pursuant to grand jury subpoenas and sealed search warrants. At the Inspector General's request, the Department sought court orders authorizing the release of sealed information that does not otherwise affect individual privacy interests so that we can include relevant information in this report. This information is included in the report where appropriate.
