Dr. Rochelle Walensky, the Centers for Disease Control and Prevention director, admitted last week that her agency made “some pretty dramatic public mistakes” handling the coronavirus, promising to “pivot” the organization so that it can better provide information to ordinary people.

But communication was never the CDC’s real problem. That was its arrogant and politicized leadership, which was unable to tell the truth. That is why no one trusts the CDC anymore or cares much for its guidance, whatever it happens to be. The cure begins with Walensky’s resignation.
