He didn't say we should do that. He was asking the doctors about using light to k**l the v***s somehow and then later asked if there was some way we could use one of the antiseptics to k**l the v***s inside the body.

You really should stop spreading lies and believing every thing you hear from the f**e media.

Here is what he said:

"Question that probably some of you are thinking of if you're totally into that world, which I find to be very interesting. So supposing we hit the body with a tremendous, whether it's ultraviolet or just very powerful light. And I think you said that hasn't been checked but you're going to test it," Trump said, looking over to Bryan.
"And then I said, supposing you brought the light inside the body, which you can do either through the skin or in some other way. And I think you said you're gonna test that, too. Sounds interesting, right?"

"And then 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, or almost a cleaning? Because you see it gets on the lungs and it does a tremendous number, so it will be interesting to check that. So that you're going to have to use medical doctors. But it sounds, it sounds interesting to me. So we'll see.

"But the whole concept of the light, the way it k**ls it in one minute, that's, that's pretty powerful."
