The Trump administration is vetting Robert Redfield, an HIV/AIDS expert at the University of Maryland Medical Center, to take over as the next director of the Centers for Disease Control and Prevention, Politico reports.

The bigger picture: The last CDC director, Brenda Fitzgerald, resigned at the beginning of the year after reports of her purchasing stock in tobacco companies surfaced. Redfield served on the advisory council on HIV/AIDS for President George W. Bush, Politico reports, and is co-founder of the Institute of Human Virology.
