New book shows how lack of quick testing compounded pandemic

The United States has now passed yet another tragic pandemic milestone. COVID-19 has now claimed the lives of more than 700,000 Americans. William Brangham talks to Dr. Scott Gottlieb, a former FDA commissioner and author of new book "Uncontrolled Spread: Why COVID-19 Crushed Us and How We Can Defeat the Next Pandemic" about where the U.S. response failed and how it can do better next time.
