Former White House chief medical advisor Anthony Fauci said Sunday on ABC’s “This Week” that there were “a number of studies that show that masks actually do work” to stop the spread of COVID-19. Anchor Jon Karl said, “There’s a new study out that suggests that masks were actually not effective, at least not in a global sense, in containing the pandemic. What is your sense looking back at all of this? Did masks prove to be less effective than you anticipated?”
