The 14th report of the committee was published in 1967 and although it claimed to deal with the Delano Grape Strike, it was an anti-communist and anti-"subversive" effort on behalf of state government. While the committee reports stated that no inference of subversive activity should be construed by mention of a person or organization in their reports, the result was less circumspect. The report of 1967 claimed that agricultural labor had been a target of Communist infiltration for thirty years due to the migratory and deprived state of agricultural workers. Chapters included the Delano Grape Strike, Spring Mobilization, The Community for New Politics, Responses from Virginia Norris Taylor and other exhibits.
