This isn't what happened. The Sirotkin post wasn't quoted at Zero Hedge until this article "Sudden Militarization of Wuhan's P4 Lab Raises New Questions About The Origin Of The Deadly Covid-19 Virus" appeared on Feb. 13, 2020. (This article establishes that if the Wuhan lab wasn't a military lab before the outbreak, it certainly became such a lab afterwards.) Earlier articles appeared on Zero Hedge on Jan. 24th, Jan. 26th, and Jan. 29th.
The email discussion between Fauci and Anderson explicitly mentioned only an article in Science Magazine, "Mining coronavirus genomes for clues to the outbreak's origins", dated Jan. 31, 2020. The article discusses zoonotic theories, but the narrative demonstrates that the zoonotic source, if any, was elusive. The author goes on to mention that "conspiracy theories also abound", and says that Richard Ebright of Rutgers generally supports the possibility that lab-leak theories could be correct, but that Peter Daszak disagrees. The question is not decisively settled, at least not in this article.
The 2012 paper seems to be in the "everybody knew but me" category....[Sky News video] ...more fascinating revelations about Fauci...
I can't find where the featured interview with Fauci came from, though. Of course Sky News is a Murdoch outlet, like Fox in the USA. And they don't say where the interview came from, though I doubt they would stoop to creating or endorsing a deep fake.
I suspect the original source might be One America News Network? They seem to have taken down the vast majority of their videos from YouTube, presumably in hopes of avoiding censorship. And I can't find the videos on Bitchute or Odysee,
