Two senior public relations experts advising the Food and Drug Administration have been ousted from their positions after fumbled communications about a blood plasma treatment for Covid-19. President Trump and the head of the F.D.A. had erroneously boasted on the eve of the Republican National Convention that the treatment sharply lowered mortality from the disease.
On Friday, the F.D.A. commissioner, Dr. Stephen M. Hahn, removed Emily Miller, the agency’s chief spokeswoman. The White House had installed Ms. Miller, who had previously worked in communications for the re-election campaign of Senator Ted Cruz and as a journalist for One America News, the conservative cable network, in this post just 11 days ago.
Dr. Hahn notified senior leadership at the F.D.A. on Friday that Ms. Miller would no longer be the official spokeswoman for the agency, and that he would be appointing someone to replace her in an interim capacity. Ms. Miller could not be reached for comment.
