The interesting thing about this one is that he seems to have hi-jacked the entire world supported search for the Covid-19 vaccine. Same 100 efforts, etc. which have been going on for some time but, now, its all American and Trump is in charge! Amazing! (I suspect there are one or two who might take exception to this one)
