In the mid-to-late 1960s the CIA initiated concerted efforts to defame independent researchers of the Kennedy assassination that contested the Warren Commission’s findings, seeking to suppress their message at every turn. By 1966 the most prominent of these researchers was New York-based attorney Mark Lane. “As part of the campaign to smear Warren Report critics,” writes historian David Talbot, former CIA Director Allen Dulles “compiled dirt on Mark Lane, whom he considered a particularly ‘terrible nuisance’ because of his growing media visibility and his influence overseas, where he was often invited to speak.” One of Dulles’ moles claimed to have located photos of Lane engaging in “’obscene acts’” with minors. “’He is supposedly Jewish,’” the informant wrote, “’but there are those who claim he is half Negro or at least has Negro blood. He is very dark complexioned, wears horn-rimmed glasses and he’s always in a hurry. My own personal opinion is that he’s deranged.’”
As Lane’s popularity developed the CIA “pressured TV and Radio programs to cancel interviews with him. When he traveled to foreign countries to speak about the Kennedy assassination, the agency sent bulletins to the U.S. embassies there announcing that Lane’s local appearances had been cancelled.”
