 He served as the 28th Governor of Ohio and as United States Secretary of the Interior.
 As Governor of Ohio, Cox sided for a time with President Andrew Johnson's Reconstruction plan and was against African American suffrage in the South, though he supported it in Ohio.

 In 1872 Cox joined the Liberal Republicans in opposition to Grant's renomination.
 In 1876 Cox returned to politics and was elected to and served one term as United States Congressman of Ohio.
