Dr. Zeke Emanuel: CDC is 'being squelched by political considerations'

Dr. Zeke Emanuel joins Andrea Mitchell to discuss President Trump's comments that young people are immune to the virus, saying that "every time the president tries to behave like a doctor, he puts his foot in his mouth and makes a mistake." He also says that the CDC's reversal on airborne transmission shows that people at the agency are "being squelched by political considerations."
