Sen. Bernie Sanders (I-Vt.) skewered the Trump administration for not doing enough to lower drug prices during a heated exchange with Health and Human Services Secretary Alex Azar on Tuesday. "My guess would be that if we get letters — and I'm sure every senator does — from people who are struggling with cancer, among other life threatening diseases, and they can't afford the medicine, I would guess that thousands of people die each year," Sanders said during a congressional hearing.
