ATLANTA — Kyle McGowan, a former chief of staff at the Centers for Disease Control and Prevention, and his deputy, Amanda Campbell, were installed in 2018 as two of the youngest political appointees in the history of the world’s premier public health agency, young Republicans returning to their native Georgia to dream jobs.
But what they witnessed during the coronavirus pandemic this year in the C.D.C.’s leadership suite on the 12-floor headquarters here shook them: Washington’s dismissal of science, the White House’s slow suffocation of the agency’s voice, the meddling in its messages and the siphoning of its budget.
In interviews this fall, the pair decided to go public with their disillusionment: what went wrong, and what they believe needs to be done as the agency girds for what could be a yearslong project of rebuilding its credibility externally while easing ill feelings and self-doubt internally.
“Everyone wants to describe the day that the light switch flipped and the C.D.C. was sidelined. It didn’t happen that way,” Mr. McGowan said. “It was more of like a hand grasping something, and it slowly closes, closes, closes, closes until you realize that, middle of the summer, it has a complete grasp on everything at the C.D.C.”
Last week, the editor in chief of the C.D.C.’s flagship weekly disease outbreak reports — once considered untouchable — told House Democrats investigating political interference in the agency’s work that she was ordered to destroy an email showing Trump appointees attempting to meddle with their publication.
The same day, the outlines of the C.D.C.’s future took more shape when President-elect Joseph R. Biden Jr. announced a slate of health nominees, including Dr. Rochelle Walensky, the chief of infectious diseases at Massachusetts General Hospital, as the agency’s new director, a move generally greeted with enthusiasm by public health experts.
