Ok so you're talking about Trump. So he asked the doctors if there is a way to inject some "almost a cleaning" agent, I don't think he said "Bleach". He also asked about using UV light. This is something that doctors have been using for many years. There are a few procedures, one involves a UV light being injected into a vein, and as the blood passes by it it cleansed, much like people with well water use UV light to cleans the water. Another method is a UV light is placed under the tongue where the blood comes very close to the surface. So Trump didn't invent this, it's been used for some time in the medical field. I was surprised at the time to Fauci didn't speak up and inform Trump that this already exited, but I think he wanted to let it hang out there sot that people like you who are not educated on these things could us it to mock Trump.
As far as injecting "an almost a cleaning" agent, this too is done in the medical field all the time through an IV drip. Trump isn't a doctor, so he is not aware of these things, but again, I'm sure Fauci is, if not, he is a pretty piss for excuse for a doctor.
