Harding appointed four Supreme Court justices, all of whom became conservative members of the Taft Court. Harding used Mellon's appointment as leverage to win confirmation for Herbert Hoover, who had led the U.S. Food Administration under Wilson and who became Harding's Secretary of Commerce.Rejecting public calls to appoint Leonard Wood as Secretary of War, Harding instead appointed Lodge's preferred candidate, former Senator John W. Weeks of Massachusetts. The law also stipulated that the president must annually submit a budget to Congress, and all presidents since have had to do so. Additionally, the General Accounting Office (GAO) was created to assure congressional oversight of federal budget expenditures. The GAO would be led by the Comptroller General, who was appointed by Congress to a term of fifteen years.
