Joke post?
This is a clear case of fraud, calculated to spread panic and chaos and take Trump down. The doctor belongs in jail.
I don’t know anything about the doc, but I do know other people who had all the covid symptoms but tested negative; the tests really are not excellent at giving the correct info you’d want to have. Knowing whether you now or recently had this covid. Either a positive or a negative test result won’t be determinate which is a pretty sorry test.
