Daniel Sheehan, a constitutional and public-interest lawyer, said in 2021 interviews that information about UFOs had been controlled by a narrow group since the end of the Second World War. He said alien technology recovered at Roswell in 1947 had been monopolized for Cold War advantage.[1][2] He made the claims while acting as lawyer for Luis Elizondo, the former Pentagon official who had gone public about the government's UFO work.[3][4] Sheehan offered no documents for these claims.[2]
Background
Sheehan was born in 1945 in Glens Falls, New York, and graduated from Harvard College (1967) and Harvard Law School (1970). He worked on cases including the Pentagon Papers, the Watergate break-in, Karen Silkwood and the La Penca bombing, and founded the Christic Institute and the Romero Institute.[1] In 1986 the Christic Institute brought a conspiracy suit on behalf of the journalists Tony Avirgan and Martha Honey. It was dismissed in 1988, and the institute was ordered to pay substantial costs.[1] Politico described him in 2021 as a lawyer with "a long history" of taking on the federal government, and as "widely viewed as a provocateur" with an abiding interest in UFOs.[4]
UFO work
Sheehan has acted as counsel to the Harvard psychiatrist John Mack and to Steven Greer's Disclosure Project.[1] In 2021 he represented Luis Elizondo in a dispute with the Department of Defense. Elizondo has said he was formerly the head of the Pentagon's Advanced Aerospace Threat Identification Program (AATIP).[1][3] In May 2021 Politico reported on Elizondo's 64-page complaint to the Pentagon inspector general, filed on 3 May, which accused officials of a coordinated campaign to discredit him.[3][4] Sheehan told the paper:[4]
- Certain Defense Department officials had been "lying about him publicly" and threatening his security clearance.
- The wider aim was to make the Pentagon clarify "what exactly is the cartography inside the Defense Department" for handling the phenomenon.
- Blaming poor coordination between offices was "the classic bureaucratic dodge".
Sheehan has also discussed Elizondo in later video interviews.[5]
The 2021 account

In an August 2021 interview summarized by Gaia, Sheehan set out a broad history of UFO secrecy:[2]
- Origins. After the Civil War, "a group of roughly 30 families" consolidated power into corporate structures that came to influence global affairs, and later propped up fascist regimes after both world wars.
- 1947. By the time of Roswell, this group was "well in control of the military-industrial complex". When technology from the crash was studied, it found a way to monopolize it "so they could use it to the advantage of the United States and the western allies in the Cold War".
- After 1991. The strategy lasted until the Soviet Union collapsed in 1991. The next step was "to prepare for an ongoing confrontation with China". Rivalry served as a reason to develop advanced weapons and aircraft, much of it, in the Gaia summary, likely "back-engineered" from alien technology.
- Tracking. Rising sightings had pushed the government to build better tracking. He cited what he called the CIA's newly formed "Electromagnetic Intelligence Center" and a "Geospatial Intelligence Center" in the Defense Department that, he said, held Roswell information.
- "UAP". Officials chose to drop "UFO" for "UAP" to shed "all the baggage" of ufology and to focus only on technology under the Defense Department's weapons program.
Gaia's summary said this shift was the catalyst for Elizondo to become AATIP's director in 2007.[2] Other accounts differ. Politico said Elizondo was assigned to the program in 2008, and Elizondo's own organization has said he took it over in 2010. The Defense Department stated in 2019 that he had no AATIP responsibilities.[3][4][6]
Context
The documented government program of that era was far smaller than Sheehan's picture suggests. AATIP began in the Defense Intelligence Agency in 2007 and was funded with $22 million over five years, ending in 2012.[6] A closely related program, the Advanced Aerospace Weapon System Applications Program (AAWSAP), was funded for fiscal years 2009 and 2010. Robert Bigelow's company was the only bidder for the contract.[8] The 2021 book Skinwalkers at the Pentagon, by AAWSAP's James Lacatski with Colm Kelleher and George Knapp, described it. The book's prepublication review took about fourteen months.[7][8]
Official findings
In March 2024 the Pentagon's All-domain Anomaly Resolution Office released the first volume of its historical report. It said it had "found no verifiable evidence for claims that the U.S. government and private companies have access to or have been reverse-engineering extraterrestrial technology".[9][10] It judged that alleged hidden programs described by interviewees either did not exist, were misidentified real national security programs, or led back to a disestablished program. It attributed much of the belief to "circular reporting from a group of individuals".[9][10]
Assessment
Sheehan offered no documents for these claims, which draw on his own experience and on what he says sources told him.[2] Parts of his account, such as the "30 families" and the Roswell monopoly, are historical assertions without cited evidence.[2] His comments on Elizondo's complaint concern a documented dispute, but the complaint's outcome and the wider claims remain unresolved.[3][4]
