There is no significant evident of efficacy to treat CV19. Who do you think didn't mean that, when they typed no evidence?
Of course it's an interesting candidate for testing, it's an anti-malarial and various countries have reported anecdotal claims about how it helps.
But there is no clinically significant..or scientifically significant evidence that it is efficacious when treating CV19.
You're splitting hairs on this, on the wrong side.
Many drugs are being tested, and we hope any/all of them are wildly effective. That Trump chose to promote one, magnified by right wing media, has caused disruptions in physician treatment protocols, has apparently resulted in at least one death, and at best has confused the public, put a run on people who really need the drug for effective treatment of lupus, etc.
It's public malpractice at a scale the nation has never seen in modern times. why defend it in any way. EVEN IF IT DOES work later, that will never change that it was wrong to do what he did, how he did it.
