Fauci said it on 60 Minutes. And he wrote it in an e-mail
The email about the mask: A woman named Sylvia Burwell asked Fauci in an email sent in February 2020 whether she should wear a mask while traveling. Fauci advised the woman, in a reply dated Feb. 5, 2020, that there is no need for her to wear a face covering because he explained, masks are meant to be worn by people who have been infected.
“Masks are really for infected people to prevent them from spreading infection to people who are not infected rather than protecting uninfected people from acquiring infection. The typical mask you buy in the drug store is not really effective in keeping out virus, which is small enough to pass through material. It might, however, provide some slight benefit in keep out gross droplets if someone coughs or sneezes on you,” Fauci wrote.
I told you the physics of it even IF the material was capable of blocking the virus, which it isn't.
So it should be clear that these officials have been lying. If you lie to the government you get fined and perhaps arrested and jailed. If the government lies to you what's the consequence?
