NEW YORK (AP) — The Senate on Wednesday confirmed Dr. Erica Schwartz as director of the Centers for Disease Control and Prevention, placing her in charge of a public health agency beleaguered by political meddling and low morale.

The front office has been staffed by political appointees with little or no training in medicine or public health. “Now, Dr. Schwartz needs to prove that her leadership will serve science and not the whims of politicians. Schwartz was the third Trump nominee for CDC director in the past 18 months.
