Our rating: Partly documented. Some of it is in the files; the bigger claims built on top are disputed or unproven. How we rate.

01 What the theory says
The theory: starting in the early Cold War, the CIA ran a program called Operation Mockingbird that recruited leading journalists and news organizations to push propaganda, and some say it never ended.
02 Why people believe it
Because there's real smoke. A Senate investigation looked at CIA use of journalists, a famous 1977 magazine article claimed hundreds of reporters had carried out CIA assignments, and the CIA's own internal list of past misdeeds, the "Family Jewels," contains a program actually named Mockingbird. Distrust of the media makes the rest feel plausible.
03 What's on the record
Each point links to a primary source or official report.
- The CIA's "Family Jewels" (a 693-page internal compilation of possibly illegal activities, released in 2007) describes "Project Mockingbird": a telephone wiretap of two Washington columnists, Robert Allen and Paul Scott, from March 12 to June 15, 1963, aimed at finding their sources for classified information. (CIA: Family Jewels)
- The Senate's Church Committee investigated CIA relationships with U.S. and foreign journalists in 1975–76. (U.S. Senate: Church Committee)
- In 1977, journalist Carl Bernstein wrote in Rolling Stone that more than 400 American journalists had carried out assignments for the CIA over 25 years. That is a journalist's account based on interviews, not a released government document.
- The phrase "Operation Mockingbird," as the name of a broad media-manipulation program, was popularized by Deborah Davis's 1979 book about Washington Post publisher Katharine Graham.
04 What's unproven or disputed
- That a single program called "Operation Mockingbird" controlled major news outlets. The only program with that name in released CIA records is the 1963 wiretap. The broad version rests on later accounts.
- That it continues today. The CIA has said it set limits on using U.S. journalists after the 1970s. Claims of ongoing control are not backed by released documents.
05 Open questions
- Which CIA-journalist relationships are still redacted in the Church Committee records?
- How many of Bernstein's '400' could be verified with documents?
- What rules govern intelligence contact with reporters today, and who audits them?
