“We’re looking at the genetic scene to see if Warren Harding and Nan Britton had a baby together and all these signs are pointing to yes,” said Stephen Baloglu, an executive at Ancestry. “The technology that we’re using is at a level of specificity that there’s no need to do more DNA testing. This is the definitive answer.”

The testing also found that President Harding had no ancestors from sub-Saharan Africa, answering another question that has intrigued historians. When Harding ran for president in 1920, segregationist opponents claimed he had “black blood.”

Republicans in Congress easily got the President's signature on their bills. They eliminated wartime controls and slashed taxes, established a Federal budget system, restored the high protective tariff, and imposed tight limitations upon immigration.

By 1923 the postwar depression seemed to be giving way to a new surge of prosperity, and newspapers hailed Harding as a wise statesman carrying out his campaign promise--"Less government in business and more business in government."

Behind the facade, not all of Harding's Administration was so impressive. Word began to reach the President that some of his friends were using their official positions for their own enrichment. Alarmed, he complained, "My...friends...they're the ones that keep me walking the floors nights!"

Looking wan and depressed, Harding journeyed westward in the summer of 1923, taking with him his upright Secretary of Commerce, Herbert Hoover. "If you knew of a great scandal in our administration," he asked Hoover, "would you for the good of the country and the party expose it publicly or would you bury it?" Hoover urged publishing it, but Harding feared the political repercussions.

Harding appointed capable men to his cabinet, including Secretary of Commerce Herbert Hoover (1874-1964), Secretary of State Charles Evans Hughes (1862-1948) and Secretary of the Treasury Andrew Mellon (1855-1937). However, he also surrounded himself with individuals who were later accused of misconduct. Harding was popular while in office, but his reputation was tarnished following his death when Americans learned of corruption within his administration–even though he had not engaged in any of this criminal activity. In one infamous incident, known as the Teapot Dome Scandal, Secretary of the Interior Albert Fall (1861-1944) rented public lands to oil companies in exchange for gifts and personal loans. (Fall was later convicted of accepting bribes and spent less than a year in prison.) Other government officials took payoffs and embezzled funds. Harding himself allegedly had extramarital affairs and drank alcohol in the White House, a violation of the 18th Amendment.
