The role of press secretary has attained a new significance during the past ten years because of presidential efforts to concentrate the focus of news on the White House. Originally intended to serve the public, the press secretary is now an important government official who not only conveys information but also explains and defends presidential actions as well. Three recent press secretaries, Ron Ziegler, Ron Nessen, and Jody Powell, illustrate this change in role definition. Prior to Watergate, Ziegler enjoyed a comfortable relationship with the press. As the tension mounted, however, he grew uncommunicative and hostile and used tactics to divert questions and to mislead the press. When Ron Nessen came to the White House, he pledged to establish a spirit of trust and credibility with the press through direct answers to their questions and by arranging frequent presidential contact with reporters. Still, at the hint of criticism of Ford, he attacked the press. The most recent press secretary, Jody Powell is praised for his candor and homespun humor. In spite of his disorganization and forgetfulness, he brings some order and harmony to press briefings. Time will bring a more accurate evaluation of his service to the reporters and the people. (MAI)
