The Office of Legal Counsel (OLC) is an office in the United States Department of Justice that assists the Attorney General's position as legal adviser to the President and all executive branch agencies. It drafts legal opinions of the Attorney General and provides its own written opinions and other advice in response to requests from the Counsel to the President, the various agencies of the Executive Branch, and other components of the Department of Justice. The Office reviews and comments on the constitutionality of pending legislation. The office reviews any executive orders and substantive proclamations for legality if the President proposes them. All proposed orders of the Attorney General and regulations that require the Attorney General’s approval are reviewed. It also performs a variety of special assignments referred by the Attorney General or the Deputy Attorney General. The Office of Legal Counsel was created in 1934 by an act of US Congress, as part of a larger reorganization of executive branch administrative agencies. It was first headed by an assistant solicitor general. In 1951, Attorney General J. Howard McGrath made it a division led by an assistant attorney, and named it the Executive Adjudications Division. This name was changed to Office of Legal Counsel in an administrative order by Attorney General Herbert Brownell Jr., issued April 3, 1953. The Office of Legal Counsel (OLC) assists the Attorney General of the United States in their function as legal adviser to the President and all the executive branch agencies, hence the appellation "the president's law firm." OLC drafts legal opinions of the Attorney General and also provides its own written opinions and oral advice in response to requests from the Counsel to the President, the various agencies of the executive branch, and offices within the Department of Justice. Such requests typically deal with legal issues of particular complexity and importance or about which two or more agencies are in disagreement.
