The emails revealed that Fauci's comments behind the scenes sometimes ran against his public remarks.
Notably, critics have taken aim at Fauci's flip on the possibility that coronavirus was made in a laboratory.
As reported by BBC, the emails raise the question of whether Fauci backed China in their denials while knowing of the legitimate possibility that it leaked from a Wuhan lab.
Fauci has denied that he was influenced by scientists at Wuhan lab.
"You can misconstrue it however you want," he said of one email exchange with Peter Daszak, head of EcoHealth Alliance, a medical non-profit organization that helped fund research at a diseases institute in Wuhan.
The emails also spotlight Fauci's intense workload as the United States' leading expert on the pandemic.
