Declassified Report: All Conditions for Lab Leak Present at Wuhan Institute of Virology

A newly declassified assessment from the Lawrence Livermore National Laboratory (LLNL) concluded that all necessary conditions for an accidental release of a lab-modified coronavirus were present at the Wuhan Institute of Virology (WIV) before the Wuhan coronavirus (COVID-19) pandemic, according to documents released by outgoing Director of National Intelligence (DNI) Tulsi Gabbard. ^[1]

The May 27, 2020 assessment, prepared by the LLNL’s Z Program, placed “equal weight” on three possible scenarios for the origin of SARS-CoV-2: lab modification and accidental leak, natural emergence or accidental release of a naturally occurring virus from a lab. Large portions of the document remain redacted, and the report stopped short of conclusively determining that a lab leak occurred. ^[2]

LLNL Assessment Details Conditions

The report identified four necessary conditions for a lab-origin scenario, according to the declassified documents. These included access to a virus closely related to SARS-CoV-2, use of a reverse genetics system to modify coronaviruses, experiments involving human ACE2 receptors and biosafety failures or lab accidents involving coronavirus research. ^[2]

“We assess all of the necessary conditions for an accidental release of a laboratory-modified coronavirus – specifically a coronavirus adapted to recognize human cell receptors – were present at the Chinese Wuhan Institute of Virology (WIV) in mid-to-late 2019,” the assessment stated. The report used “additional intelligence information from a CIA [Central Intelligence Agency] Field Analytic Conversation,” according to the documents. ^[1]

Document Dump Includes Emails, Scientific Materials

The June 18 release included internal U.S. Intelligence Community (USIC) emails, scientific publications, diplomatic cables, congressional correspondence and documents related to U.S.-funded coronavirus research in Wuhan. Among the records was a final progress report from the EcoHealth Alliance’s bat coronavirus research project that partnered with the WIV and received funding from the National Institutes of Health, much of which had been publicly available previously. ^[3]

CIA whistleblower James Erdman III testified in May 2025 that the report had concluded all prerequisite conditions for a lab leak were present but was excluded from public assessments and shared only in a classified annex the following year. ^[4] The documents also revealed that Dr. Anthony Fauci provided millions in U.S. taxpayer dollars to fund gain-of-function research at the Wuhan lab, according to Gabbard, and that Fauci worked with elements within the USIC to suppress the lab-leak theory. ^[5]

Intelligence Analysts Debated Origins in 2020 Emails

Newly released emails show intelligence officials debating gain-of-function research, reverse genetics, the virus’ furin cleavage site, and competing scientific explanations. In a March 2020 email, an analyst cautioned against setting “a very high threshold” before concluding the virus resulted from gain-of-function research, stressing that a possible laboratory origin deserved rigorous scrutiny. ^[6]

The analyst wrote, “I’m not saying WIV isn’t guilty of creating this strain, but I think we need to pin it down hard before we make this assessment. I think the [USIC] needs to be very thorough with its analysis,” according to the documents. ^[6] Internal communications also show Fauci convening a teleconference on Feb. 1, 2020, where scientists discussed evidence of gain-of-function experiments at WIV. ^[7]

Conclusion

The records provide insight into how U.S. government analysts evaluated competing origin theories during the earliest months of the pandemic, showing evidence pointing in different directions. The LLNL assessment is one of the only explanations of why some U.S. government experts believed the lab-leak scenario warranted serious consideration early on. ^[2]

The press release from Gabbard’s office accompanying the document dump went further than the documents themselves, accusing Fauci – former director of the National Institute of Allergy and Infections Diseases – of manipulating intelligence assessments, though the records show only limited interactions between intelligence officials and Fauci. ^[6] The declassified files have renewed calls from lawmakers for a full accounting of the pandemic’s origins, with Sen. Rand Paul (R-KY) issuing a subpoena for Fauci to testify. ^[8]
