Fact Check: Did most scientists on a February 2020 call think deliberate insertion of COVID-19 was possible?

Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.


Claimant: Rand Paul (R)


Claim: On a February 1, 2020, call, only two scientists concluded COVID-19 had a natural origin, while “the rest felt that deliberate insertion was possible.”


Rating: MISLEADING


Explanation: Paul selectively quoted from Anthony Fauci’s diary. Scientists considering a laboratory-related scenario possible enough to investigate did not mean they viewed deliberate genetic insertion as likely. Fauci later described the participants as more evenly divided over the virus’s possible origin.
