Graves made many successful trips to Washington to secure funds for Alabama, which he called "plum-tree-shaking expeditions," and President Roosevelt appointed him to a national advisory committee on agriculture and to an inter-regional highway committee. Graves was a strong opponent of eugenic sterilization; and in 1938, he was on hand to greet 1,200 delegates to the founding session of the Southern Conference for Human Welfare, a meeting of southern liberals, who addressed labor relations, farm tenancy, the poll tax, and constitutional rights and who condemned "enforced segregation within Birmingham." A fourth of the delegates were black.
