most troublesome aspects of the Harding presidency was that he appeared to be far more concerned with political liabilities of a scandal than in securing justice." Extramarital affairs Harding had an extramarital affair with Carrie Fulton Phillips of Marion, which lasted about 15 years before ending in 1920. The affair was revealed when Harding biographer Francis Russell, while researching his book in 1963, discovered letters from Harding to Phillips. The letters were donated to the Ohio Historical Society, and some there wanted the letters destroyed to preserve what remained of Harding's reputation. A lawsuit ensued, with Harding's heirs claiming copyright over the letters. The case was ultimately settled in 1971, with the letters donated to the Library of Congress. They were sealed until 2014, but before their opening, historians used copies at the Western Reserve Historical Society (Kenneth W. Duckett Papers) and in Russell's papers at the University of Wyoming. Russell concluded from the letters that Phillips was the love of Harding's life—"the enticements of his mind and body combined in one person," but historian Justin P.

The late president's reputation had deteriorated since his death in 1923, and many believed Britton. The public was tantalized by salacious details such as Britton's claim that the two had sex in a closet near the Oval Office, with Secret Service agents posted to ward off intruders. Although part of the public believed her, a jury found against her when she alleged she was libeled by a rebuttal of her book. According to Harding family lore, the late president was infertile and could not have fathered a child, having suffered from mumps in childhood; Britton maintained that Harding had provided child support of $500 per month for the daughter he never met, but she had destroyed romantic correspondence from him at his request. Harding's biographers, writing while Britton's allegations remained uncertain, differed on their truth; Russell believed them unquestioningly while Dean, having
