On Friday's broadcast of "CNN This Morning," CDC Director Dr. Mandy Cohen responded to some schools mandating masks by saying that "we want folks to be reacting to what they're seeing on the ground in their community and making sure that they're protecting themselves." She also stated that "masking is one of those solutions that folks could choose to use to protect themselves from this virus. It's important to know your own risk. Are you around folks who are older or who have underlying conditions? Then we need to use more layers of protection."
