Rochelle Walensky, President-elect Joe Biden’s nominee to head the Centers for Disease Control and Prevention, promised to remove all political interference from the agency.

“On my first day, I will ask Anne Schuchat, the principal deputy director, with 32 years of experience at the C.D.C., to begin a comprehensive review to ensure that all existing guidance related to COVID-19 is evidence-based and free of politics,” Walensky wrote in a New York Times op-ed.
