I fully agree that Trump could have handled the virus better. Unfortunately, ALL media attention was focused on his impeachment at the time and he was derided as a racist and tyrant for banning China travel.
He should had the courage to ban all international travel immediately when the virus got to the EU and begun to initiate national readiness. Some nations did this and suffered far less as a result. Sadly, he - like so many national leaders - took the virus seriously far too late.
