Fauci asked them to do some more investigation, which they did, and came back with a retraction when they found that the parts that they previously thought engineered had been found previously in nature.
False.
Fauci scheduled a call with them that he deemed "URGENT" in his emails, and
none of us has any idea what was discussed in that call. Your assertion that "Fauci asked them to do some more investigation" is nothing more than speculation made up out of whole cloth.
Here's what was said of Kristian Andersen's reconsideration that the virus was engineered (emphasis added).
"In January 2020, Dr. Andersen began investigating the origins of SARS-CoV-2. At every point, Dr. Andersen has objectively weighed all of the evidence available to him...Dr. Andersen’s view evolved consistent with the evidence at his disposal...Scientists must make conclusions supported by the available evidence, even when it conflicts with earlier assessments.9"
But in an email from Dr. Andersen, it said this.
"Our main work over the last couple of weeks has been focused on trying to disprove any type of lab theory..."
So from the available evidence, it would seem that Dr. Andersen sought NOT to objectively weigh evidence, but to
disprove any type of lab theory, which is demonstrably different than conducting an objective assessment. Perhaps that's what was discussed on the "URGENT" with Fauci.
This is what was said about that call.
As for the conference call of February 1, Dr. Fauci did not, in Dr. Andersen’s view, attempt to influence Dr. Andersen or any other member of the ad hoc working group of international subject matter experts with respect to any aspect of the discussion.
But Dr. Andersen wrote this himself.
There has been a lot of speculation, fear mongering, and conspiracies put forward in this space and we thought that bringing some clarity to this discussion might be of interest to Nature [sic].
Prompted by Jeremy Farrah [sic], Tony Fauci, and Francis Collins, Eddie Holmes, Andrew Rambaut, Bob Garry, Ian Lipkin, and myself have been working through much of the (primarily) genetic data to provide agnostic and scientifically informed hypothesis around the origins of the virus.
So which is it? Did Fauci not attempt to influence Dr. Andersen, who originally came to Fauci stating that he believed that the virus was consistent with being engineered, or did Fauci "prompt" (and what does that mean?) Dr. Andersen and his colleagues to change their mind?
In any event, it's clear that Fauci was involved in a much greater capacity than was let on, and it's clear from his email to Nature that Dr. Andersen understood that his directive was NOT to be objective in his assessment, but to write a paper that would disprove the lab-leak hypothesis.
