When Trump Took HCQ & Announced It Did He Know Emergency Use mRNA Shots Dependent on No Effective Therapeutic?

Translate:

Most would assume president Trump knew that using the mRNA shots (Operation Warp Speed) under Emergency Use Authorization was dependent on there being no effective therapeutic to reduce wuhan viral loads, so when he took the highly efficacious therapeutic Hyrdoxychloroquine, and announced it to the world, was it his way of saying Hydroxychloroquine should be widely used until those mRNA shots would be approved by the FDA, if that will ever happen?
