Editing Charles Evans Hughes (section)

==Return to private practice==
Hughes stayed on as Secretary of State in the Coolidge administration after the death of Harding in 1923, but he left office in early 1925.<ref>{{harvnb|ps=.|Simon|2012|p=165}}</ref> He once again returned to his law firm, becoming one of the highest-earning lawyers in the country. He also served as a [[special master]] in a case concerning [[Chicago]]'s sewage system, was elected president of the [[American Bar Association]], and co-founded the [[National Conference for Community and Justice|National Conference on Christians and Jews]].

State party leaders asked him to run against [[Al Smith]] in New York's 1926 gubernatorial election, and some national party leaders suggested that he run for president in 1928, but Hughes declined to seek public office. After the [[1928 Republican National Convention]] nominated [[Herbert Hoover]], Hughes gave Hoover his full support and campaigned for him across the United States. Hoover won the election in a landslide and asked Hughes to serve as his Secretary of State, but Hughes declined the offer to keep his commitment to serve as a judge on the Permanent Court of International Justice.<ref>{{harvnb|ps=.|Simon|2012|pp=172–174, 176}}</ref>
