Did the travel ban make coronavirus worse in the US when people rushed back from China to avoid quarantines?

Not an answerable question.  No data related to who "rushed back."

No, you're just impotently parroting yet another Democrat soundbite because you have nothing better to argue your point. You DO know that the government cannot bar Americans from entering their own country and you certainly know that Democrats insisted that there was no need for a "racist" ban in the first place because you were parroting that soundbite like a good little Democrat Useful Idiot.
