Do you think this study would have been published if Trump had loudly proclaimed that Hydroxychlorine was dangerous and should be avoided?
If your implication is that the media and the science community conspired to make the president look stupid, I think you've got a big hill to climb to prove that.
...and I think it's possible that's what we see here. An emotional decision to publish, and then no one wanted to contradict because no one wanted to be viewed as a Trump sympathizer.
