Dr. Wen is an emergency physician, CNN Health Analyst and former Baltimore Health Commissioner. We talk about mask and vaccine mandates, the return to school and work, and the Delta variant. "Unfortunately, we're in a situation now where the vaccinated are having to pay the price for the actions of the unvaccinated," she says. Wen emigrated from China as a child and relied on the public health system while she had severe asthma. She has a new memoir called 'Lifelines.' Also, Maureen Corrigan reviews the novel 'Wayward' by Dana Spiotta.
