In his younger years Lyons was a member of the Young People’s Socialist League the youth section of the Socialist Party USA.
He became critical of the Soviet Union after working there as a correspondent of United Press International.
During the early 1940s and the Second Red Scare which followed World War II, Lyons was a frequent contributor to the popular press on anti-Communist themes, targeting liberals if Lyons deemed them inadequate in their denunciations of the Soviet regime.
Lyons also wrote a biography of President Herbert Hoover.
