Fauci reflects on long career as he prepares to step down

Dr. Anthony Fauci is stepping aside after a five-decade-long career in public health. He's been one of the leading public health voices since taking the role of director of the National Institutes of Allergy and Infectious Diseases in 1984, and he's advised seven U.S. presidents. His exit comes amid the worst flu season in a decade and a new COVID surge. He joins Judy Woodruff to discuss.
