Basically what's happening in the video is Jimmy Dore going back and forth comparing statements that Fauci has made publicly with content from his E-mails. Included are statements about his stance on masks, asymptomatic spread, a possible lab leak of the virus, whether or not he has been blocked from making particular statements, and his talks with Bill Gates about a global vaccination effort. Dore claimed that Fauci lied by pointing out contradictions between his E-mails and his public statements.
To be honest, I wasn't able to read the text that was posted very well so I'm not sure how true it was. However, one particular thing I did notice was that Dore said that Fauci lied because he claimed publicly that we didn't know that 50% of infections were asymptomatic whereas he was shown to talk about asymptomatic infections much earlier in one E-mail. The thing is, Fauci didn't say in the E-mail how many infections were asymptomatic, only that there would be some. So I don't count that particular one as a lie.
Wow B.C. your eyes need testing.
