Dr. Deborah Birx
Ambassador-at-large, coronavirus response coordinator,
Since February 2020, Birx has served as a leading clinical voice in the fight against COVID-19 given her prominent position on the White House Coronavirus Task Force, along with Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. But Birx has drawn fire over actions some critics say have undermined the role of the Centers for Disease Control and Prevention during the pandemic. Birx was the U.S. global AIDS coordinator under President Barack Obama.
