Antibody testing, which I acknowledge is still being reviewed and refined, is starting to show that this virus has been spreading in major metropolitan areas in California, as well as elsewhere in the coastal US as early as December and January. Maybe before we launch these political attacks against the current administration, would could look at the leadership of these areas and their lack of any response due to their attention being focused on an impeachment that could not possibly have removed the President from office. Dianne Feinstein was too busy with the Judiciary committee and well, we know what Kamala Harris and Nancy Pelosi were doing, so California leadership was totally absent. Trump was acquitted by the Senate on February 5th.
