28 CFR § 600.9 - Notification and reports by the Attorney General.
(a) The Attorney General will notify the Chairman and Ranking Minority Member of the Judiciary Committees of each House of Congress, with an explanation for each action -
(1) Upon appointing a Special Counsel;
(2) Upon removing any Special Counsel; and
(3) Upon conclusion of the Special Counsels investigation, including, to the extent consistent with applicable law, a description and explanation of instances (if any) in which the Attorney General concluded that a proposed action by a Special Counsel was so inappropriate or unwarranted under established Departmental practices that it should not be pursued.
(b) The notification requirement in paragraph (a)(1) of this section may be tolled by the Attorney General upon a finding that legitimate investigative or privacy concerns require confidentiality. At such time as confidentiality is no longer needed, the notification will be provided.
(c) The Attorney General may determine that public release of these reports would be in the public interest, to the extent that release would comply with applicable legal restrictions. All other releases of information by any Department of Justice employee, including the Special Counsel and staff, concerning matters handled by Special Counsels shall be governed by the generally applicable Departmental guidelines concerning public comment with respect to any criminal investigation, and relevant law.
