Previously, the recommendation was to not wear face masks, so that more would be available for healthcare workers. As the behavior of the virus is studied more, and its ability to stay airborne for longer periods than previously suggested is learned, it is now recommended to use a face covering when going out in public.
DT read the script that CDC recommends it (which is good) and followed that with “I’m not going to do it” and when asked by a reporter why not he said this: “I just don’t want to be doing -- somehow sitting in the Oval Office behind that beautiful resolute desk, the great resolute desk, i think wearing a face mask as I greet presidents, prime ministers, dictators, kings, queens, I don’t know, somehow I don’t see it for myself. I just don’t. Maybe I’ll change my mind.” 🤯
