I just saw Adm. Brett Giroir who is head of the Public Health Service Commissioned Corps.(or something like that), he is an MD and Pediatrician, and currently serves as Trump's testing Czar. He had comments about hydroxychloroquine where he was very definitive. Giroir is very much in the Trump camp so there is no way these are "make Trump look bad" comments.
He said there have been 5 randomized tests of hydroxychloroquine that all showed there is no benefit. He said there might be some cases where a physician may choose to prescribe it as a treatment for Covid but he didn't know what those would might be. He said that we need to move on from it and promote other treatments.
To hear this from him, to me, closes the book on the discussion. He is very much a Trump loyalist so there is no way you can accuse him of saying it for political reasons. In fact, he is saying it in the face of many political reasons not to say it.
