JM 9-2.154
The Criminal Division is interested in obtaining the benefit of any suggestions by United States Attorney or their Assistants for changes in federal statutory law, or rules, affecting criminal prosecutions. Accordingly, United States Attorneys and Assistant United States Attorneys are encouraged to develop such proposals and to forward them for initial consideration to the Office of Policy and Legislation. The suggestions for changes in rules and legislation may also be submitted concurrently to the Legislation and Public Policy Subcommittee of the Attorney General's Advisory Committee of United States Attorneys. Suggested legislative changes should be submitted concurrently to the Office of Legislative Affairs.
United States Attorneys and their staffs are reminded that all suggestions for changes in federal criminal statutes must be communicated to the Department of Justice and not to Congress directly. Unsolicited communication to Congress of individual proposals for legislation, outside proper official channels, has the potential to cause grave embarrassment to the Department and, however well motivated, is contrary to Department policy. See also, 18 U.S.C. § 1913. See also JM 1-8.000 (Relations with the Congress).
