Again, context is a beautiful thing.
If you saw the actual press conference then you can understand what was taking place. The president posed a hypothetical. Nothing more, nothing less. If you did not see the
entire conversation that began with a fellow explaining what happens when sunlight hits the virus…… he was posing a hypothetical additional procedure to a procedure called "pathogen inactivation".

A hemopheliac childhood friend of mine lost his life to AIDS after receiving a tainted blood transfusion. Roger was as good as they come and nearly bled to death from simple cuts or internally from bruises. He was in a car wreck and needed blood. Unforunately some of what saved his life is what killed him a few years later. Pathogen inactivation helps halt that sort of thing.
I saw the entire conversation unfold and was actually surprised the yellow journalism did not pick up on something else he said before the hypothetical posed to Dr Byrx. She got a look on her face like. "let's talk about it later, the political hacks in the room probably think you want folks to drink Lysol now". I suppose saying he wants folks to be injected with Lysol was just easier to turn into a negative spin. I do recall telling Mrs Fixer "boy the press is going to freak out about that"
Dr Byrx and Dr Fauchi are HIV experts and were big time involved in the treatment of HIV so it is no longer an automatic death sentence. The lab that has been rumored to be the source of the novel corona is an HIV exploration lab among other things like many throughout the world. There are still labs on planet earth trying to stamp out HIV, Ebola, and other super bugs. Dr Byrx understood what the president was getting at. The US and other countries have done a ton to try and stamp out HIV and other bad stuff across the world.
How about this? It was the Bill Gates anti malaria group who first proposed the idea of hydroxychloroquine as a possible treatment to covid-19, not Donald Trump. Bill Gates walks on water to many people, and he has done a lot to halt the spread of malaria. So if everybody knew it was actually the Bill Gates foundation folks in lab coats touting it, perhaps many who are dead set against the idea might say "hmm, why not try It"? It was actually being tried in Brazil and was said to be 100% effective according to the Brazillian president back in March. Later after Trump touted it Twitter, Facebook and others deleted the man's boasts calling it fake news. In the mean time trials in other places were showing it worked in labs so they started trying it on people. Some it worked for. Others it did not.
Remember, context. At that point models were still showing 1-2million deaths in America. Also remember, before they knew it was a bad idea, the greatest scientific minds promoted leeches for curing sick people.
