Lancet refuses Senate inquiry on COVID-19 origins, citing hostile politics

The Lancet has refused to cooperate with a U.S. Senate inquiry into COVID-19’s origins, a decision its editor-in-chief framed as a stand against a political climate he said has turned hostile to scientists. Richard Horton said the journal had been asked for records tied to coronaviruses from 2018 through 2022 and would not participate.

The refusal puts a major medical journal at the center of a broader struggle over how far scientific institutions should go when Congress demands private emails, notes, reviewer comments and editorial decisions. Horton said he was not prepared to work with an administration he believes has attacked prominent scientists, pointing to the treatment of Anthony Fauci by President Donald Trump and his allies.

The Senate effort was not limited to The Lancet. A letter sent to Science and dated Dec. 18, 2025, was signed by Sen. Rand Paul, who chairs the Senate Committee on Homeland Security and Governmental Affairs. It demanded complete, original and unredacted records tied to coronavirus research and publishing, including internal and external emails, manuscript submissions, reviewer comments, editorial decisions and communications with named researchers and institutions. Those names included the Wuhan Institute of Virology, EcoHealth Alliance, Wellcome, Fauci, Francis Collins, Ralph Baric and Shi Zhengli.

Horton had already written in February that The Lancet had been asked for the same category of materials. He said the request reflected a persistent fixation on Wuhan and the events of late 2019, when the outbreak began in Wuhan, China. The Senate inquiry has focused in part on U.S. funding connected to a virology lab in Wuhan, keeping the origins debate tightly bound to questions of American responsibility, Chinese transparency and the politics of blame.

The scientific backdrop remains unsettled. The World Health Organization’s Scientific Advisory Group for the Origins of Novel Pathogens, a 27-member panel, said in June 2025 that the weight of available evidence still points to zoonotic spillover, either directly from bats or through an intermediate host. But the panel also said all hypotheses must remain on the table because China has not shared key genetic sequences, animal-market information or laboratory biosafety data.

At the same time, U.S. intelligence agencies have not spoken with one voice. The CIA said on Jan. 25, 2025, that a research-related origin was more likely than a natural one, but only with low confidence. NBC News reported that the FBI and the Department of Energy also leaned toward a lab leak, while other agencies favored natural spillover.

That collision between unresolved science and political scrutiny is now testing the boundaries of editorial independence. The question is no longer only where the virus began, but what rules should govern cooperation when Congress asks journals to open their archives in a dispute still shaping public trust.
