 Dr. Anthony Fauci serves as the director of the National Institute of Allergy and Infectious Diseases for nearly four decades before he stepped down at the end of 2022. He's worked with seven presidents and steered the U.S. response to countless crises from HIV to Ebola and, of course, COVID. He's out with a new bestselling memoir titled On Call, A Doctor's Journey in Public Service. Dr. Fauci, thank you for being here with us.
