Hmm, reading it again from Snopes:
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 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. So, that, you’re going to have to use medical doctors with. But it sounds — it sounds interesting to me.
The wanna be lawyer in me notices Snopes specifically uses the words "suggest".
As opposed to "said".
I mean, it was poorly said either way, but how do we know he didn't mean "Wouldn't it be great if we had an injection with a substance that could clean out the body. Like a viral equivalent to antibiotic."
