This week, Martha is joined by Dr. Anthony Fauci, director of the National Institute of Allergy & Infectious Diseases and leading member of the Trump administration's coronavirus taskforce.

Martha and Dr. Fauci discuss criticisms of the models and projections of the spread of the virus, the care that must be given to decisions to reopen parts of the country, the important role masks may play moving forward and the benefit of social distancing over hoping to form herd immunity.
