 Williams was the first presidential Cabinet member to be appointed from the Pacific Coast.
 As attorney general under President Ulysses S. Grant, Williams continued the prosecutions that shut down the Ku Klux Klan.
 He had to contend with controversial election disputes in Reconstructed southern states.
 President Grant and Williams legally recognized P. B. S. Pinchback as the first African American state governor.

 However, he argued that Spain did not have the right to execute American crew members.
 Nominated for Supreme Court Chief Justice by President Grant, Williams failed to be confirmed by the U.S. Senate primarily due to Williams' removal of A. C. Gibbs United States District Attorney at Portland, Oregon.
