[1] In 1954, Governor Robert B. Meyner appointed him New Jersey Attorney General.

Despite Meyner's efforts to continue pushing through the appointment, Richman withdrew his name from consideration.
He also served as general counsel for the New Jersey Turnpike Authority from 1958 to 1970 and as chairman of the Burlington County Bridge Commission from 1960 to 1965.
