For twenty years after World War II, the United States was in the grips of its second and most oppressive red scare. The hysteria was driven by conflating American Communists with the real Soviet threat. The anticommunist movement was named after Senator Joseph R. McCarthy, but its true dominant personality was FBI director J. Edgar Hoover, who promoted and implemented its repressive policies and laws. The national fear over communism generated such anxiety that Communist Party members and many left-wing Americans lost the laws’ protections. Thousands lost their jobs, careers, and reputations in the hysteria, though they had committed no crime and were not disloyal to the United States. Among those individuals who experienced more of anticommunism’s varied repressive measures than anyone else was Clinton Jencks.

Jencks, a decorated war hero, adopted as his own the Mexican American fight for equal rights in New Mexico’s mining industry. In 1950 he led a local of the International Union of Mine, Mill, and Smelter Workers in the famed Empire Zinc strike—memorialized in the blacklisted 1954 film Salt of the Earth—in which wives and mothers replaced strikers on the picket line after an injunction barred the miners themselves. But three years after the strike, Jencks was arrested and charged with falsely denying that he was a Communist and was sentenced to five years in prison. In Jencks v. United States (1957), the Supreme Court overturned his conviction in a landmark decision that mandated providing to an accused person previously hidden witness statements, thereby making cross-examination truly effective.

In McCarthyism vs. Clinton Jencks, Caballero reveals for the first time that the FBI and the prosecution knew all along that Clinton Jencks was innocent. Jencks’s case typified the era, exposing the injustice that many suffered at the hands of McCarthyism. The tale of Jencks’s quest for justice provides a fresh glimpse into the McCarthy era’s oppression, which irrevocably damaged the lives, careers, and reputations of thousands of Americans.

Reviews & Praise
“Raymond Caballero has written a masterful study of the intriguing Clinton Jencks. We learn not only about his labor organizing during the 1940s but also about the Red Scare, Jencks’s legal troubles and trial, and the important Supreme Court case that ensued. The research is immaculate. This will long serve as one of the most important books on labor history and anticommunism following World War II.”—Ronald D. Cohen

“Caballero has done a masterful, excellently researched job of conveying this important piece of twentieth-century U.S. history and of telling the story of Clint and Virginia Jencks, mostly unknown U.S. heroes.”—Monthly Review

McCarthyism vs. Clinton Jencks is a splendid example of high-quality research. Raymond Caballero effortlessly takes readers through a wide range of issues in his account of the forces at work in the years associated with McCarthyism and the life of Clinton Jencks. He has worked his way through complex case law, examined transcripts, notes of meetings of judges, thousands of pages of FBI reports, congressional hearings and reports, private papers and collections, newspapers, memoirs and secondary sources. He has cast a bright light on the dark arts of power. This is a book that should receive an award for the excellence of its scholarship and its contribution to our understanding of America.”—Labour History
