More than three years into the pandemic with untold millions of people dead, that question about the origin of Covid-19 remains widely disputed and fraught, with facts sparkling amid a tangle of analyses and hypotheticals like Christmas lights strung on a dark, thorny tree. One school of…

Intelligence Agencies Remain Divided Over Covid Lab Leak Theory

Intelligence agencies do not believe the case of three workers from a laboratory in Wuhan, China, who became ill in 2019 can help shed light on whether the Covid-19 pandemic originated from an accidental lab leak, according to a report made public Friday. The Office of the Director of National Intelligence released a long-awaited declassified report, which included spy agencies’ findings on the so-called lab leak theory, but the material is unlikely to satisfy many people who have been wrestling with the unanswered questions on the origins of the Covid…

U.S. Intelligence Agencies May Never Find Covid’s Origins, Officials Say

For three years, the U.S. government has been tied in knots over the origins of the coronavirus pandemic, frustrated that China’s hindrance of investigations and unwillingness to look critically at its own research have obscured what intelligence agencies can learn about whether the virus escaped from a lab. Inquiries during the Trump and Biden administrations have yielded no definitive answers. The Energy Department and the F.B.I. favored the theory that a laboratory leak may have caused the pandemic. Five intelligence bodies considered theories of natural transmission — that the coronavirus…

Republicans Push Lab Leak Theory on Covid’s Origins, but Lack ‘Smoking Gun’

WASHINGTON — The former director of the Centers for Disease Control and Prevention accused top federal health officials on Wednesday of excluding him from discussions in early 2020 about whether the coronavirus was the result of a laboratory leak — an assertion that one of the officials, Dr. Anthony S. Fauci, later said had “nothing to do with reality.” Three years into the pandemic, the accusation by the former C.D.C. director, Dr. Robert R. Redfield, put a spotlight on the lingering bitterness and partisan divisions around the scientific question of…

Hearing on Covid’s Origins Promises Politics Mixed With Substance

WASHINGTON — House Republicans on Wednesday will dig into the origins of the coronavirus pandemic in a hearing that promises to be filled with political theater alongside substantive questions about laboratory safety and what, if anything, could have been done to prevent the worst public health crisis in a century. The hearing of the Select Subcommittee on the Coronavirus Pandemic is expected to focus largely on the intensifying debate over whether Covid-19 was the result of a laboratory leak. In advance of the session, Republicans issued a memorandum critical of…

Where Did Covid Originate? Here’s What We Know and Don’t Know

WASHINGTON — The Energy Department’s conclusion, with “low confidence,” that an accidental laboratory leak in China most likely caused the coronavirus pandemic has renewed questions about what sparked the worst public health crisis in a century — and whether the virus at the heart of it was somehow connected to scientific research. Scientists and spy agencies have tried assiduously to answer that question, but conclusive evidence is hard to come by. The nation’s intelligence agencies are split, and none of them changed their conclusions after seeing the Energy Department’s findings, officials…

Lab Leak Most Likely Caused Pandemic, Energy Dept. Says, as Spy Agencies Remain Split

WASHINGTON — New intelligence has prompted the Energy Department to conclude that an accidental laboratory leak in China most likely caused the coronavirus pandemic, though American spy agencies remain divided over the origins of the virus, American officials said on Sunday. The conclusion was a change from the department’s earlier position that it was undecided on how the virus emerged. Some officials briefed on the intelligence said that it was relatively weak and that the Energy Department’s conclusion was made with “low confidence,” suggesting its level of certainty was not…

N.I.H. Leader Rebuts Covid Lab Leak Theory at House Hearing

The suspicions revolve around $8 million in grants to EcoHealth Alliance, a nonprofit that was collaborating on coronavirus research with scientists at the Wuhan Institute of Virology, in the city where the pandemic began. Late last month, an internal federal watchdog agency found that the N.I.H. had made significant errors in its oversight of those grants. In a 64-page report, the Office of Inspector General at the federal Department of Health and Human Services outlined missed deadlines, confusing protocols and misspent funds — raising and reinforcing concerns about the government’s…

Intelligence Review Yields No Firm Conclusion on Origins of Coronavirus

WASHINGTON — American intelligence agencies have not been able to determine if the coronavirus pandemic was the result of an accidental leak from a lab or if it emerged more naturally, according to declassified portions of a report to the White House that were released on Friday. The nation’s spy agencies, the Office of the Director of National Intelligence said, are unlikely to reach a conclusion without more cooperation from China or new sources of information. In a statement, President Biden said the United States would continue working to understand…
