Welp, that's why so many people think he's a moron.
Fauci has been wrong a lot. In late Feb. he stated the normal influenza season was a far bigger concern than C19, and that risk to Americans was miniscule. In the same timeframe, he and Birx stated they believed the data from China.
That's the advice Trump has been getting and explains what the left terms "downplaying" or "ignoring" C19's potential severity.
He has listened to them, and maybe he shouldn't have.
