US fraud perpetrated by the “Ohio gang” surrounding President Harding. It involved the siphoning of oil, intended for the US navy, from the oil reserves at Teapot Dome, Wyoming, to the Mammoth Oil Company. A second diversion allowed oil from Elk Hills, California, to be siphoned to the Pan‐American Petroleum and Transportation Company. Harding died before the full extent of the involvement of the Secretary of the Interior, Albert B. Fall, was exposed by Senator Thomas J. Walsh of Montana in the years 1922–24. Fall was found guilty of accepting a $100,000 bribe and imprisoned (1929–32).
