Show me the video clip where he said, "let's inject Clorox into a patient's' bloodstream'
You won't find it, because it never happened.
What he said was that they were exploring ways to inject disinfectant on localized infection sites. The thing is, people heard disinfectant and didn't think about what it meant. While we use it interchangeably with 'sterilizer' which is an aggressive substance that completely destroys organic material, a disinfectant can be a perfectly benign substance as well, such as an antiviral therapy. What he was referring to was a potential substance they were investigating that could be injected on infection sites in such a way that it neutralized COVID viruses without causing any sort of harm to the patient. While he could have perhaps elaborated a bit better on what he meant by this, that in no way justified the gross overreaction of people to that press conference. In the entire transcript of the meme you do not hear once, 'bleach', 'Clorox', or any other dangerous chemical. All he says is that they're exploring potentially wonderous therapies. He never told people to do anything, just that the government was exploring options. Here's the transcript:
