Two of the leading voices in the national debate over government surveillance programs and press freedoms will square off Nov. 11 at Duke University's Sanford School of Public Policy. Former director of the CIA and NSA Gen. Michael Hayden and Pulitzer Prize-winning journalist Barton Gellman will share a stage for the first time to discuss "Leakers or Whistleblowers? National Security Reporting in the Digital Age." The event -- which is the 2013 Robert R. Wilson Lecture -- begins at 6 p.m. in Fleishman Commons. It is free and open to the public.
