The FBI investigated John Steinbeck, believing he might be a communist.

In 1949, Orwell provided a list of communist sympathizers to a British anti-communist propaganda unit, naming figures like actor Charlie Chaplin and writer John Steinbeck. When it was made public in 2003, some called Orwell a government informant, though others blamed his tuberculosis, which would take his life a year later, while others blamed his romantic interest in the woman who asked him for the names.

J. Edgar Hoover's FBI maintained a large file on Eleanor Roosevelt, monitoring her involvement with civil rights groups, connections to progressive causes, and vocal opposition to McCarthyism. Although a formal investigation was never initiated, Hoover regarded her as a person of interest for most of her adult life.

In 1953, the writer was interrogated by the Subcommittee’s chief counsel, Roy Cohn, about communism and its impact on his work. Cohn quoted lines from poems like “Goodbye, Christ” and “Ballads of Lenin,” but Hughes denied that he was a communist, explaining that poetry should not be taken literally. “That is a poem,” he told Cohn. “One can not state one believes every word of a poem.”

Jean-Paul Sartre worked as an American correspondent for Combat, the newspaper edited by Albert Camus. While he was in the States, J. Edgar Hoover's FBI kept tabs on him, concerned that Combat was publishing unfavorable portrayals of the US.

From 1963 to 1968, the FBI surveilled Dr. King with wiretaps, hotel bugs, informants, and anonymous threats, citing concerns about Communist influence—an effort later revealed through declassified files and documented in the film MLK/FBI.

Hughes grew interested in the Soviet Union and radical politics in the early 1930s after the Communist Party of the United States defended the Scottsboro Boys, nine Black teenagers wrongly accused and convicted of raping two white women. In 1932, he lived there while working on a film that ultimately fizzled out, and returned home. In 1937, he planned to lead a tour of the country, as advertised below, but canceled it when a newspaper offered him a position reporting from the Spanish Civil War.

From exploding cigars and poisoned Cohibas to an infected scuba suit and plans to drug a TV studio with LSD, this account catalogs the CIA's strangest—and consistently unsuccessful—attempts to kill Fidel Castro over decades.

From the D.B. Cooper plane hijacking to the kidnapping of Frank Sinatra Jr. to the details about the first FBI agent killed in the line of duty, this FBI archive overviews the agency's most famous cases. Cases are organized by investigative priorities, according to the agency. Clicking any of the linked investigations takes readers to detailed articles about the cases, some of which remain unsolved.

Narrated through firsthand interviews, The Agent tells how Jack Barsky (born Albrecht Dittrich) spent a decade undercover as a Soviet KGB "illegal" in the US, balancing dual identities in Queens—from insurance programmer to deep-cover spy—until a crisis forced him to choose between loyalty and family.

The French philosopher was a long-time ardent supporter of communism and the USSR. He finally spoke out against the movement with the 1956 Soviet invasion of Hungary, saying that the move was "made possible by 12 years of terror and imbecility."

Sam Dickstein remains the only known member to have served in Congress while actively being on the payroll of a foreign adversary. The revelation came in 1999 upon the release of thousands of KGB documents.

The writer belonged to the French Communist Party and the Algerian Communist Party in the mid-1930s, but he was eventually expelled for refusing to downplay objections to French colonialism. By the time he published "The Rebel," he was vocally anti-communist, believing it was a utopian ideology that often relied on violence.

Oliver Stone's film "JFK" (1991) imagined the 1963 assassination of President John F. Kennedy as the result of a conspiracy by US government agents. Before the film, this belief was not common, but it became widely adopted afterward. The film's impact contributed to the release of major CIA files in subsequent decades.

Comey worked at Bridgewater Associates for three years before becoming the director of the FBI in 2013. Comey has said the company's tradition of "probing," or intense questioning, can be more intense than government hearings. During his time at Bridgewater, Comey led multiple investigations into employee conduct—particularly that of former executive Eileen Murray.

In February 1950, Senator Joseph McCarthy infamously proclaimed that he had a list of communist State Department employees. The next month, cartoonist Herbert Block published a cartoon in the Washington Post featuring a reluctant elephant (the mascot of the Republican Party) being pushed to stand on a wobbly tower labeled “McCarthyism.”

Dustin Hoffman and Robert Redford spent months shadowing the real Carl Bernstein and Bob Woodward—working at The Washington Post, living with Bernstein's family, and studying their mannerisms—to bring authentic nuance to their portrayals of Watergate's investigative journalists.

Soviet infiltration—most notably by Klaus Fuchs—smuggled detailed implosion-design and hydrogen‑bomb data from Los Alamos to Moscow, cutting the USSR’s development time by at least a year and enabling their first atomic test in August 1949.

Some believe JFK's assassination was orchestrated by larger networks rather than a lone shooter. Skeptics wondered how one unknown man could kill the most powerful person in America, and believed the CIA, FBI, or Soviet government played a role in the murder.

The 73-year-old dictator of the Soviet Union died March 5, 1953, officially from a stroke, on top of nearly a decade of significant medical issues. But evidence suggests the longtime leader might have been poisoned less than a week before at an intimate gathering of Stalin's closest confidantes and advisors. Explore the current evidence for Stalin's alleged murder here.

The poem’s portraits of people on society's fringes—including vivid descriptions of drug use, psychiatric wards, and homosexuality—led to its seizure by US Customs agents and the arrest of its publisher Ferlinghetti. The American Civil Liberties Union defended both in a landmark trial that ruled the book was not obscene.

The two were close friends, sometimes collaborating throughout the 1940s, but the release of Camus' 1951 book, "The Rebel," led to a schism over differing views on communism.

The unpublished "The Holy, Beat, and Crazy Next Thing" was found in the belongings of Paul Castellano, who was murdered in 1985.
