FBI file

Bernstein was involved in numerous left-wing causes and organizations since the 1940s, at which time the FBI began its decades-long monitoring of Bernstein's activities "for his ties to communist organizations." In the 1980s, through the Freedom of Information Act, he was able to view his FBI file, which was over 800 pages long. In the early 1950s, he was briefly blacklisted by the United States Department of State and CBS, but he was never asked to testify before the House Un-American Activities Committee.
