WASHINGTON (AP) — A former senior adviser to Dr. Anthony Fauci was indicted on federal charges alleging he conspired to hide his communications related to COVID-19 research as the pandemic raged across the country, the Justice Department said Tuesday.

Dr. David Morens, 78, is accused of using his private email account to intentionally circumvent public records laws while employed at the National Institutes of Health. The Justice Department alleges that he concealed or destroyed records of discussions related to COVID-19 research grants, including an effort to revive a controversial coronavirus grant.

"These allegations represent a profound abuse of trust at a time when the American people needed it most — during the height of a global pandemic," Acting Attorney General Todd Blanche said in a statement Tuesday. "Government officials have a solemn duty to provide honest, well-grounded facts and advice in service of the public interest — not to advance their own personal or ideological agendas."

Morens faces charges of conspiracy against the United States; destruction, alteration or falsification of records in federal investigations; concealment, removal or mutilation of records; and aiding and abetting, according to a Justice Department news release. If convicted, he could face decades in prison. An attorney for Morens declined to comment.

The indictment reflects Republicans' long-held belief that the federal government covered up key information about COVID-19 as the pandemic unfolded. Despite numerous probes, the origins of COVID have never been proven. Scientists are unsure whether the virus jumped from an animal, as many other viruses have, or came from a laboratory accident. A U.S. intelligence analysis released in 2023 said there is insufficient evidence to prove either theory.

Blanche said Morens' alleged conduct was part of an effort to "suppress alternative theories" about COVID-19's origins. The Justice Department also accused Morens of having an improper relationship with a collaborator, including allegedly accepting a gift of wine and discussing COVID-19 research and potential publications in a prominent medical journal.

The indictment follows a probe by House Republicans into the origins of the COVID-19 pandemic that scrutinized Morens' email communications and accused him of intentionally concealing records. In congressional testimony, Morens denied attempting to evade federal transparency laws by using his personal email.
