Dr. Oz's Amazing Medicine Show

Houston has one of the highest populations without health insurance in the country. On Saturday, physician and TV host Dr. Mehmet Oz and hundreds of volunteer health-care practioners held a one-day free clinic in the city. The response was the largest ever reported for a non-emergency health event. Dr. Oz spoke with CNN's Don Lemon about the importance of the event.
