Former NIAID Adviser David Morens Pleads Guilty to Conspiracy in Scheme to Conceal COVID-Related Communications

David M. Morens, a former senior adviser at the National Institute of Allergy and Infectious Diseases, pleaded guilty on Tuesday to a federal conspiracy charge stemming from efforts to hide communications about coronavirus research grants during the COVID-19 pandemic by using his personal email account.

Morens, 78, of Chester, Maryland, entered the plea in U.S. District Court in Greenbelt to one count of conspiracy to commit offenses and to defraud the United States. He faces a maximum of five years in prison and a fine of up to $250,000 when he is sentenced on November 12. Morens served as a senior adviser in NIAID’s Office of the Director from 2006 until 2022, working under then-Director Anthony Fauci.

According to the plea agreement and court filings, Morens and two co-conspirators agreed during the pandemic to evade Freedom of Information Act requests and Federal Records Act requirements after the National Institutes of Health terminated a grant titled “Understanding the Risk of Bat Coronavirus Emergence.” The grant had been awarded to a New York-based nonprofit later identified in related congressional records as EcoHealth Alliance, whose work included sub-awards connected to research at the Wuhan Institute of Virology. The termination followed allegations linking the laboratory to the emergence of COVID-19.

In anticipation that their communications would be sought through FOIA, Morens and the others agreed in writing to conduct discussions using his personal Gmail account rather than his official NIH email. Over that channel they exchanged non-public NIH information, discussed efforts to influence the agency to restore funding, shared drafts of letters to NIH leadership, and back-channeled information to a senior NIAID official. Prosecutors stated that Morens also pledged to help counter the narrative that the virus had leaked from a laboratory.

As part of the same plea, Morens admitted receiving illegal gratuities from one of the co-conspirators. Court records describe gifts that included bottles of wine delivered to his home in 2020, characterized in correspondence as related to his “behind-the-scenes” assistance. The co-conspirator also offered additional items of value. Morens was not separately charged with a gratuities offense.

Morens has publicly supported the natural-origin explanation for COVID-19. In a 2020 article titled “The Origin of COVID-19 and Why It Matters,” published in the American Journal of Tropical Medicine and Hygiene, he and co-authors argued that available virologic, epidemiologic, and ecologic data pointed to the virus evolving from bat coronaviruses, consistent with a zoonotic emergence. The timing of his private communications about restoring the terminated grant and countering the laboratory-leak hypothesis overlapped with this public advocacy.

U.S. Attorney Kelly O. Hayes for the District of Maryland announced the plea alongside officials from the FBI and the Department of Health and Human Services Office of Inspector General. Defense counsel stated that by pleading guilty Morens had taken responsibility for his actions. The case forms part of broader federal scrutiny of pandemic-era decision-making, grant oversight, and the handling of records related to the origins of COVID-19.
