America's doctor is being taken to task by a group of his peers. Dr. Mehmet Oz hosts the TV program "The Dr. Oz Show." He is also vice chairman of the Surgery Department at Columbia University. And now 10 well-regarded physicians from all over the country are calling on Columbia to drop Dr. Oz from its faculty. The group penned a letter to the school, and they write this (reading) Dr. Oz has repeatedly shown disdain for science and for evidence-based medicine. They go on to say that he promotes quack treatments for financial gain. Columbia responded by saying that it is committed to upholding faculty members' freedom of expression. To discuss this letter and the dock at the center of the controversy now is Michael Specter. He profiled Mehmet Oz for The New Yorker magazine back in 2013. Welcome to the program.
