Okay but there are actually good reasons to test hydroxychloroquine, as it is effective against viruses with relevant similarities to Covid-19. The same is not true for chocolate milk.

To address the elephant in the room: yes, Trump did come out in favor of hydroxychloroquine, but his opinion on medical issues is literally meaningless noise in both the informational and auditory senses of the phrase. We certainly shouldn't be pursuing hydroxychloroquine because Trump said to, but there are other good reasons to at least investigate it.
