This story isn’t what CNN is trying to present it as. So basically, it appears you have a doctor being a snake oil salesman using a treatment to sell something bogus to people trying to protect themselves from getting infected and was not actually acting as a treating doctor, and was exploiting the President’s words as a ruse to get people to buy in.
CNN then takes this incident to create a bogus story to try to damage the President as though he is somehow responsible for this individual’s actions as though he is a player in this drama, when he has nothing to do with it.
