David Grusch: The UAP Whistleblower Who Testified to Congress

David Grusch served as an officer in the U.S. Air Force and later worked in the intelligence community, including at the National Geospatial-Intelligence Agency and the National Reconnaissance Office. By his own account he was assigned to represent his agency on the Pentagon’s UAP Task Force and its successor, and in that role he began hearing from people who described a hidden, decades-long effort to retrieve and reverse-engineer craft that were not made by humans.

In 2022 Grusch filed a whistleblower complaint with the Intelligence Community Inspector General, alleging that information about these programmes was being illegally withheld from Congress and that he had suffered reprisals for raising it. After leaving government service, he went public in June 2023. His story first appeared in The Debrief, in an article by journalists Leslie Kean and Ralph Blumenthal, and was followed within days by a long television interview with Ross Coulthart on NewsNation.

On 26 July 2023 Grusch testified under oath before a subcommittee of the House Committee on Oversight and Accountability, alongside former Navy pilots David Fravor and Ryan Graves. He told the members that the U.S. government possesses recovered craft and what he called non-human biologics, and that some people had been harmed in efforts to keep this secret. He said many details could only be given in a classified setting, and he declined to answer several questions in open session for that reason.

Grusch has not publicly produced documents, photographs, material samples or named first-hand witnesses. He has said that he interviewed dozens of officials with direct knowledge, and that he passed names, locations and programme details to the Inspector General and to congressional intelligence committees in closed briefings. None of that material has been released. Before he spoke publicly, his statements went through the Pentagon’s pre-publication security review, which cleared them for release. That review checks for classified information; it does not confirm that a statement is true.

Supporters point to his career and security clearances, to the fact that he made his claims under oath, and to reports that the Inspector General judged his original complaint to be credible and urgent. That assessment, as described by Grusch and his lawyer, concerned the reprisal and withholding complaint and its procedural seriousness, not a finding that non-human craft exist. Several members of Congress said after closed briefings that they took his information seriously, but they did not describe any physical proof.

The central weakness of the testimony is that it is second-hand. Grusch has said repeatedly that he has not personally seen a recovered craft or body. What he offers is his assessment of what other people told him, filtered through programmes he says he was not allowed to enter. Without the underlying witnesses coming forward, or documents being declassified, outsiders have no way to weigh the quality of those accounts.

The Department of Defense said shortly after his public appearance that its investigators had not found verifiable information to substantiate claims that programmes to possess or reverse-engineer extraterrestrial materials had existed in the past or exist now. It also noted that Grusch had not brought his specific claims to its All-domain Anomaly Resolution Office (AARO) before going public.

In March 2024 AARO published Volume 1 of its report on the historical record of U.S. government involvement with UAP. It said it had found no evidence that any U.S. government investigation, research, or programme had confirmed that any UAP sighting represented extraterrestrial technology, and no evidence of a hidden reverse-engineering effort. The report argued that many modern claims trace back to a small circle of people repeating and amplifying each other’s beliefs, and to misunderstood but real classified programmes, such as aircraft development and intelligence projects that are secret for ordinary reasons.

The most common conventional reading is that Grusch sincerely believes what he has been told, but that the stories reaching him were rumours, misinterpretations of genuine secret projects, or accounts that grew as they were passed along. Compartmented programmes are, by design, hard to verify from the outside, and that same secrecy makes it easy for speculation to fill the gaps. On this view no one needs to be lying for an elaborate but unfounded story to circulate inside government circles.

Grusch and his supporters reject AARO’s conclusions. They argue that AARO could only examine programmes it was given access to, that a truly hidden effort would not appear in official records, and that the office did not interview every witness Grusch identified. Some lawmakers have pushed for legislation that would force the disclosure of UAP records across government, partly in response to his testimony. Critics reply that the absence of evidence after years of searching is itself informative.
