FWIW: 'Promising' is a pretty accurate paraphrase of “I think that’s a great thing to look at", which is what the NY Times quotes him as saying.

I'll assume no negative intent and that English is not your first language, because there's a big difference between calling something "promising" versus "interesting to look at".

I am a native English speaker and would agree that "interesting to look at" is perhaps a little weaker than "promising." Maybe 20% weaker, as if there's a scale.

However, the transcript from the NY Times and BBC--not to mention my comment above--also has him saying "a great idea to look at" in the same response, which I do think is equivalent to 'promising'.

This is an inevitable consequence of telling others to be careful with their words.

How, exactly? In context, a treatment being "interesting to look at" is interesting because you think it might work. Isn't that what "promising" means in the same context? You seem to be hiding behind the presidents imprecision here. I genuinely don't understand how someone could look at the video of that press conference and think the president was not celebrating the idea of possibly finding a cure by injecting disinfectants into people's bodies.

Perhaps you could demand that first of the president of the united states, and then perhaps, secondarily of some random poster on hacker news?

You're the one being irresponsible here, in mounting any kind of defense of what Trump said. It was total crazy talk. Tell the truth.
