As the Newseum opens “Reporting Vietnam,” a new exhibit marking the 50th anniversary of the Vietnam War, veteran broadcaster Haney Howell – the last CBS News bureau chief in Saigon before the city fell in 1975 – speaks with the Newseum Institute’s Gene Policinski about what it was like to report in Vietnam and in neighboring Cambodia. Howell, now journalism professor emeritus at Winthrop University, also discusses the differences, both good and bad, in reporting from today’s global conflict zones.
