Here's the part that I find important, I too have highlighted it in red as it's referenced to the part in blue -
"So I asked Bill a question some of you are thinking of if you're into that world, which I find to be pretty interesting. So, supposing we hit the body with a tremendous, whether its ultraviolet or just very powerful light, and I think you said, that hasn't been checked but you're gonna test it. And then I said, supposing it brought the light inside the body, which you can either do either through the skin or some other way, and I think you said you're gonna test that too, sounds interesting. And I then I see the disinfectant, where it knocks it out in one minute, and is there a way you 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'd be interesting to check that. So you're going to have to use medical doctors, but it sounds interesting to me, so we'll see. But the whole concept of the light, the way it goes in one minute, that's pretty powerful."
So the definition , "Something like that" means, "Something along those lines; something similar to that."
Now, those that support Trump and those with TDS probably read the transcript subjectively. I read it objectively.
I see it as he's waffled on about light etc.. all a bit in broken English. Then he mentions disinfectant and how it wipes germs out rapidly. Then he wonders if something along those lines; something similar to that can be injected. We're adults, we know that viruses are treated with vaccines and Trump wants someone to work like disinfectant against Coronavirus.
Now, Trump may not sound like the brightest, but in my opinion, those who think he meant injecting disinfectant into their body as a vaccine is stupid.

Take "Something like" out of the transcript, I would agree he said inject the disinfectant.
It's really hard to believe you're doubling down on defending that insane clown.
If he had wanted to say vaccines, he would have said vaccines, but instead, he said disinfectant. That's objective.
