During his World War II service in the U.S. Army, Muse, assigned to
Washington, D.C., bought a farm in
Manassas, Virginia (then a distant suburb). He founded and published a local newspaper, the
Manassas Messenger, selling it in 1950 (it later became the
Journal-Messenger) but continuing a related printing business until 1966. During the 1950s and early 1960s, Muse wrote a weekly "Virginia Affairs" column for
The Washington Post. It chronicled problems resulting from racial segregation and policies of the
Byrd Organization. He also criticized the
NAACP for pushing for rapid school desegregation, especially in
Prince Edward County. Muse also wrote about Southern affairs in
The Nation and
The New Republic. After both a three-judge federal panel and the Virginia Supreme Court declared most of the
Stanley Plan (a package of laws designed to support Massive Resistance) unconstitutional on January 19, 1959 (birthday of
Robert E. Lee and a Virginia state holiday), Muse (who considered himself a "fighting moderate" rather than a liberal) directed the Southern Leadership Project of the Southern Regional Council, an early private civil rights organization. For four years Muse toured the South urging voluntary compliance with court desegregation orders. President
John F. Kennedy also appointed him to a commission to monitor racial equality in the armed forces. in 1961, and
Ten Years of Prelude (also about Massive Resistance) in 1964. He also published
Tarheel Tommy Atkins (1963) about World War I. He later published
The American Negro Revolution: From Nonviolence to Black Power, 1963-1967. His last book was
The Twentieth Century as I Saw It (1981). ==Death and legacy==
