Michael Shellenberger

Journalist

Michael Shellenberger published and testified about alleged Immaculate Constellation UAP claims from whistleblower materials without official confirmation

Disclosure Rating — 4/10

Michael Shellenberger is the founder of Public and a public-policy author whose UAP role centers on publication, congressional testimony, and advocacy around anonymous-source allegations rather than on personal government service or first-hand UAP observation.123

  Verified biography

Shellenberger's congressional biography lists him as founder of Public from 2023, president and founder of Civilization Works from 2024, C.B.R. Chair of Politics, Censorship, and Free Speech at the University of Austin from 2023, president and founder of Environmental Progress from 2016 to 2024, and president and co-founder of the Breakthrough Institute from 2003 to 2015.1

The same biography lists books including San Fransicko, Apocalypse Never, and Break Through, as well as a 1996 master's degree in cultural anthropology from the University of California, Santa Cruz, and a 1993 bachelor's degree from Earlham College.1

Those records place his verified background in journalism, public policy, environmental advocacy, and institutional commentary, not in the Department of Defense, the Intelligence Community, or AARO.12

  Immaculate Constellation publication

On October 8, 2024, Public published Shellenberger's article alleging that a government whistleblower had revealed the name of an unacknowledged special access program for UAP; the article said Shellenberger did not claim to know what UAP are and framed the allegation as a transparency and oversight issue for Congress.4

His later written testimony identified the alleged program as Immaculate Constellation and attributed the core claims to a current or former U.S. government official acting as a UAP whistleblower, plus other existing or former government officials who spoke to Congress or Public.3

In that account, the whistleblower report alleged that Immaculate Constellation began in 2017 after public reporting on AATIP, functioned as a central or parent USAP, and consolidated UAP observations from tasked and untasked collection platforms.35

  Testimony and congressional record

Congress.gov records the November 13, 2024 House Oversight hearing titled "Unidentified Anomalous Phenomena: Exposing the Truth" and lists Shellenberger as a witness identified as founder of Public.2

At that hearing, Congress.gov linked Shellenberger's biography, written statement, truth-in-testimony filing, the hearing transcript, and supporting documentation that included the Immaculate Constellation report entered by Rep. Nancy Mace.265

Shellenberger's written and oral testimony said the alleged program included imagery intelligence, measurement and signatures intelligence, defense human-intelligence reports, and incidents involving objects described as spheres, discs, ovals, triangles, boomerangs, arrowheads, and irregular forms.35

The supporting document in the hearing record is the public PDF cataloged here as the Immaculate Constellation memo, but the open record does not publicly identify its author or provide independently verifiable source files for the alleged incidents.267

  Official responses

DoD spokesperson Sue Gough told Shellenberger that the department had no present or historical record of any SAP called Immaculate Constellation, and an ODNI FOIA release later repeated that denial while summarizing press coverage of the allegation.38

AARO's March 2024 historical report, which predated Shellenberger's article, said AARO found no evidence that any U.S. government investigation confirmed a UAP sighting as extraterrestrial technology and no empirical evidence that the U.S. government or private companies had reverse-engineered extraterrestrial technology.9

The same AARO report assessed that named or described hidden UAP reverse-engineering programs raised by interviewees either did not exist, were misidentified sensitive national-security programs, or were unwarranted and disestablished efforts.9

ODNI and DoD's FY 2024 UAP annual report, published one day after the House hearing, said AARO received 757 UAP reports for the reporting period, resolved 118 cases to prosaic objects, finalized 174 additional cases as prosaic, and had discovered no evidence of extraterrestrial beings, activity, or technology.10

  Contested claims

The verified part of Shellenberger's UAP role is procedural: he published the October 2024 allegation, testified about it before House Oversight, and helped put related materials into the congressional record.4235

The unverified part is substantive: public sources do not establish that Immaculate Constellation exists as described, that it contains a hidden UAP archive, or that it has been unlawfully withheld from Congress.89107

Post-hearing questions from Rep. Eric Burlison asked Shellenberger about his sources, the alleged database, primary records, and DoD's denial; Shellenberger answered that he had multiple vetted sources, would not identify them beyond his testimony, had nothing to add about the database or structure, and had nothing beyond what he shared with the committee.7

The balanced reading is that Shellenberger became the main public conduit for the Immaculate Constellation allegation, while the public record still rests on anonymous sourcing, congressional interest, and official denials rather than public corroborating evidence.42387
