Why some of Biden's top doctors are wearing masks in "low" COVID areas

Two of the Biden administration's top doctors now say they are now choosing to wear masks indoors even in communities officially deemed to have "low" levels of COVID-19.

"I've been masking more, partially because I've really had engagements that I've really wanted to get to, and didn't want to have to cancel," Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, said last week at an event hosted by the Milken Institute in Los Angeles.  

Photos posted by Walensky during her trip out West showed her masking during several stops in Southern California, including meeting with CDC staff.
