Actually, if you have a link for exactly what she is saying and the context for "knew" I'd appreciate it. I assume this is during interviews as she goes around on her book tour. In some ways I see her as a sympathetic figure. If you look at the organizational hierarchy of the task force during that critical time she was essentially responsible for much of it and in charge of none of it. But asymptomatic spread was her pet thing and the way she tried to push on that a) messed up the data reporting in b) ways that didn't really track asymptomatic spread. So she made matters worse for herself. So if she, like Billy Barr, has written a book and is going around on the mea culpa cable news/talk show circuit, saying inflammatory things those need to be looked at critically. I mean, if her book is just another "here's how I kept my moral compass in the Trump White House shit storm" that's a pretty well worn path at this point and a missed opportunity. If the book instead focuses on administratively here's how things worked-or didn't-from her perspective that's more useful. But she was pretty much walled off from the vaccines. That was Miley and Jared (presumably there to hoover up any loose change).
