To make up for the months where US health officials said not to wear masks, now some are saying it's best to wear two masks. So after a few months, it'll average out to having advocated wearing one mask the whole epidemic.
There's still been no reckoning that the 6 foot distance rule was dubious if not an outright sham, only marginally based on science, practically difficult to maintain, and probably only meaningful when combined with mask wearing, overall people avoidance, handwashing, etc.
The basic idea of not getting too close to others who might be infected is of course common sense useful. But masks largely block the virus from spreading in the environment, while the 6' rule just hopes you are far enough away that any viral dispersal drops before it reaches you. Ventilation patterns, people moving around, and especially aerosol dispersal make that mostly a matter of luck.
Fauci now comes out and says the obvious, that the Trump response led to large numbers of preventable deaths. And Fauci was complicit. Frequently wrong and a Trump enabler, Fauci should be retired (I would have just fired him, but that's not Biden's style).
