Flint pediatrician on "red flags" of tainted water, speaking up for children
Dr. Mona Hanna-Attisha, a pediatrician at Flint's public hospital, was the first person to scientifically prove a direct link between Flint's 2014 water switch and elevated levels of lead in local children. Hanna-Attisha joins "CBS This Morning" to discuss what she chronicles in her new book, "What the Eyes Don't See: A Story of Crisis, Resistance, and Hope in an American City." She calls Flint a "crime scene" and says the city has PTSD from the water disaster.
