Fred Letts’s three terms in Congress were a legislative interlude in his long and distinguished legal career. In 1931, President Hoover appointed Letts to the U.S. District Court of Washington, D.C. His notable cases include work on the Teamster’s Board of Monitors—resulting in him recusing himself from the 1960 civil trial of James Hoffa—and a criminal conviction of author George Sylvester Vierck on charges of being a Nazi agent.
