The only thing I'll say is that Trump did ban travel from China to the US very early on but after that he blew everything to do with the virus. Obviously he didn't get the potential magnitude of it.
The fucking hilarious and/or xenophobic part about that "fact" is that trump banned travel from China/Asia
after the following:
a) Confirmed cases in the US
b) confirmed outbreak in Italy and by extension Europe
c) tons of people had already come to the US from China and US citizens were still allowed to come.
So, lets be clear, while he did ban travel from China, he did it FAR after it would have done any good at all to stop the spread of the virus in the US.
It is literally another example of a dumb ass thing he did just because he is a racist.
