Sunny Hostin talks about why the location of her novel "Summer on Sag Harbor" is significant. The writer, attorney and co-host of "The View" shares what she learned about its history over the 20 years that she has summered there and why it is a unique part of the Hamptons. "Black folks were only allowed to buy in certain areas in this country, especially beachfront, and Sag Harbor was one of those areas," she said. "They started a group of investors with Black lawyers and doctors and teachers and nurses, then they bought this stretch of land in the late '40s, early '50s, and basically built a community and they were welcomed."
