Trump should definitely not ever, ever, EVER have endorsed a drug that was not thoroughly tested for the purpose he was recommending it.

that was insane.

Everything that followed makes sense...of course the entire scientific and medical world fell over itself to stop people trying to use it.....until it was tested and proven effective and safe for the purpose.

* incidentally, I have no idea why a US President would ever endorse any drug at all, let alone one that was untested.

Trump should not have endorsed a treatment because he "felt" it was good. This forced scientists/media to issue warnings when people were dieing from preemptive self medication. It is really easy to overdose, and has complications for people with cardiac issues.
