What was the subject of the major American political scandal of the 1920s known as the Teapot Dome Scandal?

The Teapot Dome scandal was a bribery scandal involving the administration of United States President Warren G. Harding from 1921 to 1923. Secretary of the Interior Albert Bacon Fall had leased Navy petroleum reserves at Teapot Dome in Wyoming, as well as two locations in California, to private oil companies at low rates without competitive bidding.

The leases were the subject of a seminal investigation by Senator Thomas J. Walsh. Convicted of accepting bribes from the oil companies, Fall became the first presidential cabinet member to go to prison; no one was convicted of paying the bribes.

Before the Watergate scandal, Teapot Dome was regarded as the "greatest and most sensational scandal in the history of American politics". It damaged the reputation of the Harding administration, which was already severely diminished by its controversial handling of the Great Railroad Strike of 1922 and Harding's veto of the Bonus Bill in 1922.

Congress subsequently passed legislation, enduring to this day, giving subpoena power to the House and Senate for review of tax records of any U.S. citizen regardless of elected or appointed position. These resulting laws are also considered to have empowered the role of Congress more generally.
