would do if he knew of some great scandal, whether to publicize it or bury it. Hoover replied that Harding should publish and get credit for integrity, and asked for details. Harding stated that it had to do with Smith but, when Hoover enquired as to Daugherty's possible involvement, Harding refused to answer. Teapot Dome The scandal which has likely done the greatest damage to Harding's reputation is Teapot Dome. Like most of the administration's scandals, it came to light after Harding's death, and he was not aware of the illegal aspects. Teapot Dome involved an oil reserve in Wyoming which was one of three set aside for use by the Navy in a national emergency. There was a longstanding argument that the reserves should be developed; Wilson's first Interior Secretary Franklin Knight Lane was an advocate of this position. When the Harding administration took office, Interior Secretary Fall took up Lane's argument and Harding signed an executive order in May 1921 transferring the reserves from the Navy Department to Interior. This was done with the consent of Navy Secretary Edwin C. Denby. The Interior Department announced in July 1921 that Edward Doheny had been awarded a lease to drill along the edges of the Elk Hills naval reserve in California. The announcement attracted little controversy, as the oil would have been lost to wells on adjacent private land. Wyoming Senator John Kendrick had heard from constituents that Teapot Dome had also been leased, but no announcement had been made. The Interior Department refused to provide documentation, so he secured the passage of a Senate resolution compelling disclosure. The department sent a copy of the Teapot Dome lease granting drilling rights to Harry Sinclair's Mammoth Oil Company, along with a statement that there had been no competitive bidding because military preparedness was involved—Mammoth was to build oil tanks for the Navy as part of the deal. This satisfied some people, but some conservationists, such as Gifford Pinchot, Harry A. Slattery, and others, pushed for a full investigation into Fall and his activities. They got Wisconsin Senator Robert M. La Follette to begin a Senate investigation into the oil leases. La Follette persuaded Democratic Montana Senator Thomas J. Walsh to lead the investigation, and Walsh read through the truckload of material provided by the Interior Department through 1922 into 1923. The documents included a letter from Harding stating that the transfer
