I'd guess this has already been posted here since it's from March 31 but "Marcus Zervos, infectious disease doctor for Henry Ford Health System, said they had seen success with hydroxychloroquine therapy in a number of COVID-19 patients. He said those given the drug were able to get off a ventilator and out of the hospital faster."

I saw an article yesterday about the number of different strains of the virus. I figure this might explain why some are reporting success using HCQ and an antibiotic and others aren't. There's no 1 size fits all in medicine.
As for the hits on Fox and Ingraham calling it a game changer,
I don't watch her show but I'd bet she said the same thing the President did, that it is a "potential" game changer. A lot of the "news media" like to twist words. They claim "Trump called chloroquine a game changer" when in reality he said it might be a game changer... Anything to hurt Trump. And the usual suspects lap it up and say "yeah! he said....." without ever bothering to look into what was actually said.
