Naw bro he literally said
“ STOP BUYING MASKS!
They are NOT effective in preventing general public from catching #Coronavirus,”
Mostly the bolded part makes the point. He tried to convince the public that masks weren’t effective because they had a depleted stockpile, by saying masks aren’t effective (which isn’t true.)
so he purposely misled the public he’s supposed to protect. This was end of Feb so it was definitely known that the virus was likely passed through aerosolization and certainly through droplets.
I had this understanding based on the data and studies coming out of China and bought my first masks in the last week of Jan. As the Surgeon General of the United States, he understood this as well by Feb 29
