Moves the United States Marshals Service (USMS) out of the Department of Justice and places it under the judicial branch, changes who appoints and supervises its leaders, and creates a new oversight Board to manage the Service’s Director and policies. It revises how U.S. marshals are appointed and their terms, transfers certain authorities from the Attorney General to the Chief Justice (with Board consultation), adds an explicit list of law‑enforcement tasks USMS may perform at the Attorney General’s request and the Director’s approval, and updates other statutes for consistency.
