On February 1, 2020, Fauci and his boss, NIH Director Dr. Francis Collins, and at least eleven other scientists participated in a conference call during which several of them warned that COVID-19 may have leaked from a lab in Wuhan, China - may have been intentionally genetically manipulated.
Three days after the call, four participants from the call (Scripps Research virologist Kristian Andersen, University of Sydney virologist Edward Holmes, Tulane School of Medicine virologist Robert Garry, University of Edinburgh virologist Andrew Rambaut and Columbia University virologist Ian Lipkin) seemingly discarded their concerns over a lab-leak, and drafted "The Proximal Origin of SARS-CoV-2," which they sent to Fauci and Collins.
Also heavily involved (yet not credited) was Dr. Jeremy Farrar, the current Chief Scientist at the World Health Organization.
....As a related aside - the Washington Examiner revealed last week that two authors of "Proximal Origin" who initially expressed concerns over a lab-leak and then changed their tune (Anderson and Garry), received millions in NIH grants under Fauci.
