JM 1-6.111
The term "employee" is defined to include "all officers and employees of the United States appointed by, or subject to the supervision, jurisdiction, or control of the Attorney General of the United States, including United States Attorneys, U.S. Marshals, U.S. Trustees and members of the staffs of those officials." 28 C.F.R. 16.21(b). A state or local law enforcement officer assigned to a joint task force or other working group is included within this definition to the extent the subpoena or demand relates to his or her work on the task force. However, if authorization is sought for testimony by a federal employee employed by an agency other than the Department of Justice, Department policy requires that such authorization be obtained from the employing agency even if the employee is a member of a joint team such as an Organized Crime Strike Force. Also included in the definition are former Department employees in cases in which the subpoena or demand seeks testimony as to information acquired while the person was employed by the Department.
