Scott Pelley on Bari Weiss & His Last Days at '60 Minutes'

It's hard to overstate the impact of "60 Minutes" on journalism. It's the most-watched television-news program in America. Since its debut on CBS in 1968, it's been the home of some of the most-storied broadcast journalists, from Mike Wallace and Ed Bradley to Lesley Stahl, Anderson Cooper and, until this past week, Scott Pelley.
