Their Claims
David Grusch served 14 years as a US Air Force intelligence officer, reaching the rank of Major, with a combat tour in Afghanistan. He subsequently served as a senior civilian intelligence official at the GS-15 level (equivalent to a full-bird Colonel) at the National Geospatial-Intelligence Agency (NGA) from 2021 to 2023. From 2019 to 2021, he was the National Reconnaissance Office's (NRO) representative to the Unidentified Aerial Phenomena Task Force.
Grusch stated that in the course of his official duties, he was informed of a "multi-decade UAP crash retrieval and reverse-engineering program" to which he was denied access. He claimed to have interviewed over 40 witnesses with direct knowledge of these programs over a four-year period. Based on these interviews and documentation he reviewed, Grusch alleged that the US government possesses recovered craft and materials of "non-human origin."
His claims extend beyond simple crash retrieval. Grusch stated that elements of the US government had systematically thwarted congressional oversight regarding these programs, keeping elected representatives in the dark about their existence and scope. He alleged that the programs operate within legacy Special Access Programs (SAPs) that predate modern oversight frameworks, effectively existing outside democratic accountability.
On the physics of UAP, Grusch referenced the "holographic principle" and the possibility that the operators of recovered craft could be "projected from higher dimensional space to lower dimensional" space. He stated that "it is a well-established fact, at least mathematically and based on empirical observation and analysis, that there most likely are physical, additional spatial dimensions." He also indicated that the operators could be interdimensional beings or potentially time-travelers, though he framed these as theoretical possibilities rather than confirmed conclusions.
In 2022, while at NGA, Grusch filed a federal whistleblower complaint with the Intelligence Community Inspector General (ICIG). The ICIG found the complaint "credible and urgent" in July 2022 and a summary was immediately submitted to the Director of National Intelligence, Avril Haines; the Senate Select Committee on Intelligence; and the House Permanent Select Committee on Intelligence.
In March 2025, Representative Eric Burlison (R-MO) appointed Grusch as a Special Advisor on UAP matters to the Task Force on the Declassification of Federal Secrets, a four-month appointment beginning April 1, 2025. In this role, Grusch advises Burlison and his staff on navigating the intelligence community and formulating questions for future congressional UAP hearings.

Key Arguments & Evidence They Cite
- 40+ witnesses with direct knowledge: Grusch stated he interviewed over 40 individuals currently or formerly involved in classified UAP programs, conducted over a four-year period while serving in official intelligence roles
- ICIG "credible and urgent" determination: The Intelligence Community Inspector General independently assessed his complaint and found it met the threshold of "credible and urgent," the highest classification for whistleblower complaints forwarded to congressional intelligence committees
- Denied access to programs: Grusch claimed he was specifically denied access to UAP-related Special Access Programs despite holding appropriate clearances and having a need-to-know based on his UAP Task Force role — suggesting deliberate compartmentalization
- Non-human biologics: Testified under oath that people with direct program knowledge assessed that biological material of non-human origin had been recovered alongside craft
- Congressional oversight failure: Alleged that these programs have systematically evaded congressional oversight for decades, operating within legacy SAP frameworks that predate modern oversight requirements
- Multi-decade timeline: The programs Grusch described are not recent — they allegedly span multiple decades, suggesting a long-running retrieval and analysis effort
- Recovered craft and materials: Claimed the US government possesses "quite a number" of recovered craft of non-human origin, not merely fragments or debris
- Holographic principle and extra dimensions: Referenced established mathematical frameworks (holographic principle, extra-dimensional physics) as potential explanations for the nature and origin of UAP operators
- Legislative obstruction: Cited specific members of Congress (Rogers, Turner) as actively blocking UAP transparency legislation, which he argued would be unnecessary if there were truly nothing to disclose
Where They've Said It
- The Debrief — June 5, 2023: Leslie Kean and Ralph Blumenthal broke Grusch's story in an article titled "Intelligence Officials Say U.S. Has Retrieved Craft of Non-Human Origin." This was the first public disclosure of his allegations. Major outlets including The New York Times, Washington Post, and Politico were offered the story but declined to publish it.
- NewsNation interview — June 2023: First on-camera interview discussing his whistleblower complaint and allegations
- House Oversight Committee testimony — July 26, 2023: Testified under oath before the Subcommittee on National Security, the Border, and Foreign Affairs, alongside Navy pilots Ryan Graves and David Fravor. This was the most significant congressional UAP hearing in decades.
- Joe Rogan Experience #2065 — November 2023: Extended three-hour interview providing his most detailed public discussion of classified programs, threats he received, legislative obstruction, and his certainty about non-human intelligence
- Intelligence Community Inspector General complaint — Filed 2022, deemed "credible and urgent" July 2022: The formal whistleblower filing that initiated the chain of events leading to his public disclosures
- UAP Disclosure Act of 2023 (Schumer Amendment) — Grusch assisted in drafting provisions of the National Defense Authorization Act of 2023 related to UAP reporting, including whistleblower protections and exemptions to non-disclosure agreements
The Counterargument
- Pentagon denial: The Department of Defense stated that its inquiries into Grusch's claims "had not turned up any verifiable information" substantiating the existence of UAP crash retrieval or reverse-engineering programs. The All-domain Anomaly Resolution Office (AARO) released a report in March 2024 stating it found no evidence of such programs.
- No first-hand evidence presented publicly: Grusch's testimony is based on what others told him — he has not personally handled recovered craft or materials. Critics note the distinction between first-hand and second-hand testimony.
- Scientific skepticism: Physicist Sean Carroll stated that Grusch was "talking about the holographic principle and extra dimensions and stuff like that" which should "set off your alarm bells," concluding that Grusch "has all of the vibes of a complete crackpot." Carroll and other physicists argue that invoking extra dimensions without testable predictions is not meaningful science.
- Source credibility questions: Some critics question whether Grusch's 40+ witnesses could all be reliable, noting the possibility of shared delusion, disinformation campaigns, or misidentification of classified conventional programs as non-human technology.
- Mainstream media caution: The New York Times, Washington Post, and Politico all declined to publish Grusch's story, suggesting their editorial standards found the evidence insufficient. The story was ultimately published by The Debrief, which critics note is a UFO-friendly outlet.
- Classification as shield: Some argue Grusch's inability to provide classified details in public settings conveniently prevents verification — he can make extraordinary claims while citing classification as the reason he cannot provide extraordinary evidence.
- Personal credibility attacks: The Intercept reported on Grusch's psychiatric history, though also noted that he maintained his security clearance throughout, which would not typically be the case if his judgment were considered impaired.

Background
David Grusch served as a combat veteran in Afghanistan and held senior intelligence positions at the National Reconnaissance Office (NRO) and the National Geospatial-Intelligence Agency (NGA). He was a representative on the UAP Task Force from 2019 to 2021, where his role involved coordinating intelligence on unidentified anomalous phenomena across agencies.
What He Disclosed
In June 2023, Grusch went public with allegations that he had been informed by colleagues with direct knowledge of a "multi-decade UAP crash retrieval and reverse-engineering program" run by the U.S. government. He stated:
- The U.S. government has retrieved craft of non-human origin
- "Non-human biologics" have been recovered from crash sites
- He was denied access to these programs despite his role on the UAP Task Force
- Multiple individuals with direct knowledge shared "compelling evidence in the form of photography, official documents and classified oral testimony"
- The programs have been hidden from congressional oversight
Congressional Testimony — July 26, 2023
Grusch testified under oath before the House Oversight Committee in a hearing titled "Unidentified Anomalous Phenomena: Implications on National Security, Public Safety, and Government Transparency."
Key Moments
"I was informed in the course of my official duties of a multi-decade UAP crash retrieval and reverse-engineering program to which I was denied access." — David Grusch, sworn congressional testimony, July 26, 2023
When asked about non-human biologics, Grusch confirmed that this "was the assessment of people with direct knowledge on the program I talked to, that are currently still on the program."
The hearing produced audible gasps in the room. According to witnesses, "there was definitely a gasp and everyone was definitely a little bit shocked" during the non-human biologics testimony.
Retaliation
Grusch testified he faced "very brutal" retaliation after coming forward, including:
- Professional reprisals
- Personal harassment
- Attempts to discredit him
- A psychiatric detention incident (later reported by The Intercept), after which he notably retained his security clearance — suggesting the intelligence community found no basis to revoke it
Impact on Other Officials
Grusch's testimony prompted strong reactions from members of Congress:
- Rep. Tim Burchett (R-TN) — Became one of the most vocal advocates for UAP transparency, stating the Pentagon is hiding information
- Rep. Eric Burlison (R-MO) — Said he would be "extremely livid" if the government had discovered advanced propulsion technology, describing classified UAP videos shown in closed-door briefings as depicting objects "defying physics"
- Sen. Marco Rubio (R-FL) — Stated the UAP issue "keeps me up at night" and confirmed he had spoken with additional firsthand witnesses
- Rep. Mike Gallagher (R-WI) — Suggested UAPs could represent "ancient civilization" technology and pushed for faster disclosure
Why This Matters for Consciousness Research
Grusch's testimony is significant for consciousness research because:
- If non-human intelligence is confirmed, questions about the nature of their consciousness become central
- The interdimensional hypothesis for UAPs directly connects to consciousness studies
- The level of government secrecy around these programs parallels the classification of consciousness research (Gateway Process, Stargate)
- Multiple UAP researchers have noted that the phenomenon appears to have a consciousness component — craft that respond to observers, entities that communicate telepathically
The Counterargument
- Grusch acknowledged his testimony was based on what others told him, not personal firsthand observation of craft or biologics
- The Pentagon has denied the existence of any verifiable evidence of extraterrestrial technology
- PBS analysis noted that "whistleblower testimonies did not change our basic understanding of UFOs"
- Some critics argue Grusch's psychiatric detention raises questions about reliability (though his retention of clearance argues against this)
- No physical evidence has been publicly produced
