It doesn't have to be "fake news" for the left to use COVID 19 to tank the market. You're seeing an example of it in Rubin's comments. "Never let a crisis....etc".
I don’t think that is the main element here—having to shut down the country for an apparent 100-year health crisis is. Nobody doubts or really question s but that they are trying to undermine Trump at every move. But she is talking about conservatives being deluded at risk to their lives. And the typical Freeper mouthing off about this not being a legit health crisis by my observation seems to be relatively safely tucked away in Podunk, Flyover Land.
