I'm not so sure that what Trump said was taken out of context as you claim it was.
No matter how you look at it, it seems he said something really stupid.
I guess I wasn't clear enough.
Trump did say something stupid. But to me it sounded like he was inferring things and asking for confirmation from his advisers.
He did not explicitely say "you need to inject bleach" or something like that. He literally said "Is there a way we can do something like that?" before his comment about the desinfectant, and "it'd be interesting to check that" and "sounds interesting"afterwards. So that's what I think it's been taken out of context.
For the record, I'm not a Trump supporter.
