Anne Schuchat has been tapped to lead the Centers for Disease Control and Prevention following the resignation of the former director Wednesday.

Dr. Brenda Fitzgerald resigned from the role after Politico reported that she had invested in tobacco stocks after becoming the agency’s director. The CDC carries out a wide range of public heath efforts, including those aimed at smoking cessation. Fitzgerald’s resignation came two days after a new secretary was sworn in to the Department of Health and Human Services, which oversees the CDC and other agencies such as the Food and Drug Administration and the National Institutes of Health.
