Just occurred to me (sorry if I missed someone mentioning this earlier) that Joe Biden stood on a stage with Donald Trump for 90 minutes speaking loudly at each other -- on Tuesday night.
Is Trump tested daily? Was he tested (negative) before the debate?
I think there's legit concern that the POTUS may have infected Biden. Hard to tell, but looks like they were about 10 feet apart (?). With Trump yelling at/toward Biden for 90 minutes, I suspect the chances of transmission are pretty decent.
FYI: Trump reporting mild symptoms.
