Dr. Ashish Jha, former White House COVID-19 response coordinator, says pandemic ‘probably was a lab leak’

Ashish Jha, who served as the White House COVID-19 response coordinator during the Biden administration, told reporters he has shifted toward the lab-leak theory as the most plausible explanation for the origins of COVID-19.

Ashish Jha, the former White House COVID-19 response coordinator during the Biden administration, said he now believes the origins of the coronavirus pandemic were “probably” linked to a lab leak.

Jha, speaking Sunday in remarks reported by the New York Post, said he has reversed his earlier position and now favors the lab-leak theory as the most plausible origin story. The report describes his shift as a change from prior public framing of the most likely explanations for the outbreak.

Jha’s remarks arrive amid continuing disagreement in the United States over whether SARS-CoV-2 emerged naturally or resulted from a research-related incident. Multiple investigations over the years have produced differing assessments, and U.S. agencies have previously described uncertainty in how the virus first spread to humans.

The White House role Jha previously held placed him at the center of the federal COVID-19 response. As COVID-19 policy shifted from emergency actions to longer-term management, officials and public health leaders continued to revisit questions about the pandemic’s earliest days, including the extent to which officials in Beijing, U.S. experts, and international investigators could determine a definitive origin.

In the New York Post report, Jha’s updated view is presented as an additional data point in a debate that has been tied to questions of intelligence reporting, biosafety practices, and how quickly early outbreak information became available. His statement does not, according to the report, identify new evidence beyond his assessment of what is “probably” most plausible.

With no associated official policy action described in the reporting, Jha’s comments appear to be limited to his personal judgment on the origin question rather than a government determination. The statement nonetheless adds to renewed public attention on the lab-leak theory ahead of further scrutiny by U.S. officials and independent researchers.

Why It Matters

Jha’s prior White House role makes his shift notable in a long-running, politically charged origins debate.
The statement adds to uncertainty over what the U.S. government and scientific community can definitively conclude about early outbreak circumstances.
Public attention to the origins question can affect how investigations, oversight inquiries, and future risk assessments are discussed.
Because the reporting describes a personal assessment rather than an official determination, the next steps would likely be further review by institutions that compile evidence and assessments.
