NEW YORK (AP) -- White House chief of staff can be a thankless job, and the Discovery TV network is poised to explain why.
Discovery said Wednesday that it will air a special series "The Gatekeepers," about the people in charge of keeping a presidential administration running, sometime next year. Discovery isn't sure yet how long it will be.
Filmmakers are seeking interviews with all the living former chiefs of staff, and have talked with former presidents Jimmy Carter and George H.W. Bush. Former Vice President Dick Cheney, who was President Ford's chief of staff, talks about what experience in that job he blames for his first heart attack.
French brothers Gedeon and Jules Naudet, who made the film "9/11," and former ABC producer Chris Whipple are behind the project.
