A former senior adviser to Anthony Fauci has admitted in court that he deliberately hid government emails to obstruct inquiries into the origins of the Covid-19 pandemic.
David Morens, 78, who worked under Fauci at the National Institute of Allergy and Infectious Diseases (NIAID) from 2006 to 2022, pleaded guilty on August 18 in federal court in Greenbelt, Maryland, to one count of conspiracy to commit offences and to defraud the United States.
He faces a maximum sentence of five years in prison and a fine of up to $250,000, with sentencing set for November 12. He had been indicted in April on five counts.
The US Department of Justice said the scheme was designed to evade the Freedom of Information Act and the Federal Records Act in connection with communications about coronavirus research grants.
Morens told a federal judge in Maryland that he diverted emails he considered politically sensitive to a personal Gmail account in order to avoid their possible public release under freedom-of-information laws.
Prosecutors said he discussed scrubbing government accounts of communications that could fuel debate over the virus’s origins.
Republicans in the House of Representatives investigated Morens’ email traffic in their inquiries into the pandemic’s origins prior to the indictment, accusing him of deliberate document concealment. The House Select Subcommittee on the Coronavirus Pandemic subpoenaed his personal account and released about 30,000 emails in 2024.
At a subcommittee hearing on May 22, 2024, Morens said his avoidance of transparency law had been “wrong” but denied knowing that emails from his government account counted as federal records.
Much of the case centred on his exchanges with Peter Daszak, then president of EcoHealth Alliance, the organisation that received US funding linked to bat coronavirus research at the Wuhan Institute of Virology.
The plea documents name neither man nor the organisation, referring instead to “Co-Conspirator 1” and “Company 1”, though the descriptions match both. The grant at issue, Understanding the Risk of Bat Coronavirus Emergence, was cancelled by the National Institutes of Health over allegations the virus had emerged from the Wuhan institute.
As part of his plea, Morens also admitted conspiring to accept illegal gratuities from the same co-conspirator. The Department of Justice said these included wine delivered to his Maryland home for his “behind-the-scenes shenanigans” and offers of meals at Michelin-starred restaurants in Paris, New York and Washington.
Prosecutors said Morens then identified an official act by which he could deserve the gift: Writing a commentary in a prominent medical journal arguing that Covid-19 had natural origins.
Prosecutors have not accused Fauci himself of wrongdoing in this case.
The guilty plea comes amid continued scrutiny of the early pandemic response and the laboratory-leak hypothesis.
On July 29 the White House formally identified a laboratory incident in Wuhan as the most likely origin of Covid-19, accusing Fauci, the National Institutes of Health and the World Health Organization of having downplayed the theory.
That reporting also noted that Morens had written in 2022 that he had “deleted everything with [EcoHealth] people from my entire Outlook,” an action the US House select subcommittee viewed as the destruction of federal records.
Morens had previously described his actions as a misguided attempt to shield Fauci from threats and to limit what he regarded as misinformation.
Fauci has repeatedly denied knowledge of his adviser’s efforts to conceal correspondence, telling the House subcommittee in June 2024 that he had known nothing of Morens’ dealings with Daszak, EcoHealth or his emails.
On July 29 Fauci invoked the Fifth Amendment, which protects against self-incrimination, more than 100 times before the Senate Committee on Homeland Security and Governmental Affairs. The committee voted along party lines on August 6 to hold him in contempt of Congress.
Committee chairman Rand Paul referred the matter to the Department of Justice, arguing that Fauci could not rely on the Fifth Amendment because Joe Biden had granted him a pre-emptive pardon in January 2025. Fauci’s lawyer David Schertler called the vote “a crude political stunt”.
Morens is to be sentenced by a federal district judge in Maryland.
For years the laboratory-leak hypothesis was widely dismissed by public-health officials, mainstream media outlets and social-media platforms as a baseless conspiracy theory.
Fact-checkers labelled discussions of a possible lab origin as misinformation, while major technology companies removed posts, suspended accounts and restricted visibility for scientists, journalists and ordinary users who raised the possibility.
Only later did intelligence assessments, congressional investigations and internal communications reveal that the theory had been taken seriously in private by some of the same figures who publicly rejected it.
On August 2 Ashish Jha, who served as White House Covid-19 response coordinator under US president Joe Biden from April 2022, said the most likely origin of the pandemic was a laboratory leak in Wuhan. Jha told CNN his view had shifted since he entered the White House and stressed that no one outside China could be certain.
The 520-page House COVID report says: lab leak most likely, no scientific basis for the 2m rule, mask mandates ineffective, lockdowns did more harm than good, and the Biden administration used likely unconstitutional methods to combat misinformation. https://t.co/vPRwvzjJQV
