It would appear that the venue for the debate in Cleveland was the source for the outbreak of infections affecting Trump and many of those associated with him. It is quite possible that the air-exchange system was not up to par within the building.
In any event, if people were seriously concerned about such a venue, then those managing the building should have issued N95 masks to each one entering (since the average mask is worthless). That could have possibly prevented POTUS and FLOTUS (and others) from being infected. At the same time testing positive means nothing, since 80% who test positive do not show symptoms.
By the same token Mr. Trump -- for whatever reason -- has allowed Fraudulent Fauci to control the narrative as well as the treatments. Had Trump appointed Zelenko as his primary adviser, and announced from the Oval Office that he was 100% behind Zelenko's HCQ package -- which would be freely available to the public at no cost, he could have saved hundreds of thousands of lives. Indeed, his whole family and staff should have had immediate access to Zelenko's package at all times (which includes zinc sulphate as a critical component).
It has now been reported that Trump is on Fauci's (and Gilead's) Remdesivir (which costs $3,500 per series of treatments, and is not even half as effective as HCQ). Also on some other *experimental* treatment (which a president should not be fooling around with).
Which means that Mr. Trump sabotaged himself unnecessarily when Zelenko had already advised him back in March, 2020. And Zelenko is not the only one who had good success with this inexpensive package. Many doctors highly recommended HCQ.
