Richmond helped found The Daily People's World which was a leftist newspaper in San Francisco, and he served as its executive editor. Later, Richmond said of the anti-Communist campaign of Senator Joseph McCarthy, "I think that a lot of people were silenced, and their withdrawal from social commitment extended long afterward." Richmond left the party in 1968 after his paper criticized the Soviet Union for the invasion of Czechoslovakia, though he remained a Marxist. His autobiography, "A Long View From The Left," was published in 1973.
