Read this, then youll know.
It looks like hydroxychloroquine might help to relieve symptoms, which I suppose could lead to better clinical outcomes. Remdesivir also could help, but was still in clinical trials for the purpose of gaining eventual FDA approval. In other words, no miracle drug is about to hit the scene.
I do have to wonder who brought the hydroxychloroquine to the president's attention. Did he go by media reports without consulting his scientific advisors? Did they give him wrong advice? I find either possibility hard to believe, but I suppose it's possible.
