Trump DID speculate about the possibility of injecting disinfectants into the body, and suggested looking into it as a treatment for COVID-19:
“I see the disinfectant, where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning? Because you see it gets in the lungs and it does a tremendous number on the lungs. So it would be interesting to check that.”
It's true that Trump didn't specifically mention bleach, but one of the primary disinfectants that was being talked about at the time, that could kill COVID-19 on surfaces, was bleach, as well as less-toxic ammonia-based disinfectants. Nevertheless, since he didn't specifically say "bleach", it's true that people shouldn't have claimed that he did.
So when you say that Trump said to inject bleach, that is false. Sorry but that's just the facts.
