I wish I could blame the lack of reasonable mask guidance on the previous administration, but last I checked the official CDC guidance was that they'd rather have the general public tie the tattered remnants of their Def Leopard Hystaria tour t-shirt over their face than an FDA approved K/N95 mask. We've had a good supply of masks available for many months (Although you have to be careful about your supply chain). Of the many, many unforced errors of this pandemic, this may be the most baffling to me.
