Along with Secretary of the Treasury Andrew Mellon, Coolidge won the passage of three major tax cuts. Using powers delegated to him by the 1922 Fordney–McCumber Tariff, Coolidge kept tariff rates high in order to protect American manufacturing. Coolidge appointed one individual, Harlan Fiske Stone, to the Supreme Court of the United States. Stone was Coolidge's fellow Amherst alumnus, a Wall Street lawyer, and a conservative Republican. Stone was serving as dean of Columbia Law School when Coolidge appointed him to be attorney general in 1924 to restore the reputation tarnished by Harding's Attorney General, Harry M. Daugherty. In his veto message, Coolidge expressed the belief that the bill would do nothing to help farmers, benefiting only exporters and expanding the federal bureaucracy. Congress did not override the veto, but it passed the bill again in May 1928 by an increased majority; again, Coolidge vetoed it.
