He stated his certs as: Clinical pathology (studies disease in a lab by observing fluid and tissues) and skin pathology.
I'm sure he's great at what he does and Mayo is a great learning hospital, but no mention of specializing/experience in respiratory diseases, which is what Covid/SARS is.

So the next time you have a urinary tract infection, are you going to go see an ear-nose-throat doctor because they have Mayo certifications in bacterial infections? Or maybe the top veterinarian specializing in urinary tract infections?

Point is: medicine is acutely specific and specialized for a reason. And the fact that he's interviewing with the (stopthemandate) network shows some potential bias. (I'm just applying that critical thinking and analysis everyone is so jazzed about lately.)
I don't care one way or the other what other people decide, there are potential consequences no matter what one does.
