 the Office of the Deputy Attorney General, the Office referred that evidence to appropriate law enforcement authorities, principally other components of the Department of Justice and to the FBI. Appendix D summarizes those referrals.

To carry out the investigation and prosecution of the matters assigned to him, the Special Counsel assembled a team that at its high point included 19 attorneys—five of whom joined the Office from private practice and 14 on detail or assigned from other Department of Justice components. These attorneys were assisted by a filter team of Department lawyers and FBI personnel who screened materials obtained via court process for privileged information before turning those materials over to investigators; a support staff of three paralegals on detail from the Department's Antitrust Division; and an administrative staff of nine responsible for budget, finance, purchasing, human resources, records, facilities, security, information technology, and administrative support. The Special Counsel attorneys and support staff were co-located with and worked alongside approximately 40 FBI agents, intelligence analysts, forensic accountants, a paralegal, and professional staff assigned by the FBI to assist the Special Counsel's investigation. Those "assigned" FBI employees remained under FBI supervision at all times; the matters on which they assisted were supervised by the Special Counsel.

During its investigation the Office issued more than 2,800 subpoenas under the auspices of a grand jury sitting in the District of Columbia; executed nearly 500 search-and-seizure warrants; obtained more than 230 orders for communications records under ; obtained almost 50 orders authorizing use of pen registers; made 13 requests to foreign governments pursuant to Mutual Legal Assistance Treaties; and interviewed approximately 500 witnesses, including almost 80 before a grand jury.

From its inception, the Office recognized that its investigation could identify foreign intelligence and counterintelligence information relevant to the FBI's broader national security mission. FBI personnel who assisted the Office established procedures to identify and convey such information to the FBI. The FBI's Counterintelligence Division met with the Office regularly for that purpose for most of the Office's tenure. For more than the past year, the FBI also embedded personnel at the Office who did not work on the Special Counsel's investigation, but whose purpose was to review the results of the investigation and to send—in writing—summaries of foreign intelligence and counterintelligence information to FBIHQ and FBI Field Offices. Those communications and other correspondence between the Office and the FBI contain information derived from the investigation, not all of which is contained in this Volume. This Volume is a summary. It contains, in the Office's judgment, that information necessary to account for the Special Counsel's prosecution and declination decisions and to describe the investigation's main factual results.
