 Secretary of Commerce was considered a minor Cabinet post, with limited and vaguely defined responsibilities, but Hoover decided to accept the position.Hoover's progressive stances, continuing support for the League of Nations, and recent conversion to the Republican Party aroused opposition to his appointment from many Senate Republicans.To overcome this opposition, Harding paired Hoover's nomination with that of conservative favorite Andrew Mellon as Secretary of the Treasury, and the nominations of both Hoover and Mellon were confirmed by the Senate.
