What is the biggest scandal of the Harding administration involved whom?

The biggest scandal of the Harding administration was the Teapot Dome scandal, which involved Secretary of the Interior Albert B. Fall. Fall was found to have secretly leased federal oil reserves at Teapot Dome, Wyoming, and Elk Hills, California, to private oil companies in exchange for bribes. This corruption led to a significant public outcry and tarnished Harding's presidency, although he himself was not directly implicated. Fall became the first cabinet member to be imprisoned for misconduct while in office.
