WASHINGTON, Sept 1 (Reuters) - U.S. President Donald

Trump on Monday called on pharmaceutical companies to justify

the success of their drugs intended to treat COVID.

He said there is disagreement on whether the drugs saved

lives.

"With CDC being ripped apart over this question, I want the

answer, and I want it NOW," Trump wrote on Truth Social. "I have

been shown information from Pfizer ( PFE ), and others, that is

extraordinary, but they never seem to show those results to the

public."
