I still haven't seen a full account of what happened at the CDC in early 2020, why they required all samples to go through them and would not condone the WHO test. It took a lab in Washington to run tests semi-illegally to find the first non-imported case in the US.The information was out there, and the epidemiologists knew what was happening in other countries. For political reasons, it was downplayed to the rest of us. As Trump said, "It'll just magically go away".
Trump knowing what was going on and downplaying it is well documented now, but happened later.
