Fauci’s diary provides the clearest insight yet into classified CIA intelligence on the origins of COVID-19. It includes the revelation that the Wuhan lab was experimenting with coronaviruses sampled from pangolins, which harbor coronaviruses closely related to COVID-19. The CIA officer informed Fauci that the Wuhan lab had collected pangolin viruses in the field and received other pangolin viruses from a research group in Beijing. But by the time the university’s data was published in full, it was clear the pangolin viruses would not settle the origins question. “It was very similar to some of the very disappointing briefings that I had previously received in prior years from the CIA,” Fauci noted.
