As one of the co-signers of the letter to Science asking for increased investigation into the origins of SARS-CoV-2, I want to make two points: first, thanks very much for the two episodes of TWiV when you met with the WHO committee and with Robert Garry. These episodes are doing a great service for all to clarify these issues. Second, as a co-signer or the letter to Science, I’d like to explain my motivation for adding my name: namely, I thought the letter would have the effect of prompting more funding for searching for natural viruses in animal reservoirs, which I personally have always assumed represent the origin of SARS-CoV-2 infections in humans. Perhaps naively, I did not anticipate that the letter would be used to promote the lab origin hypothesis. Looking back on the wording of the letter, however, I now think that I should have realized this would happen and should have been more proactive — either not signed the letter at all or else requested more wording changes to make my position clear.
