The leak of the campaign papers first came to public attention in June 1983, with the publication of Laurence Barrett's "Gambling With History: Reagan in the White House", an in-depth account of the Reagan administration's first two years. Comments on the matter by David Stockman, made at an Optimist Club lunch in Cassopolis, Michigan, on the day of the debate, noted that in assisting with Reagan's preparations, Stockman had had access to a "pilfered" copy of Carter's briefing book; these remarks had been reported only in local newspapers. The publication of Barrett's book saw efforts by Jody Powell and Patrick Caddell to push the issue onto the press agenda, ultimately leading to Reagan asking the Justice Department to "monitor" the issue. The president denied having any knowledge about briefing papers his campaign was thought to have obtained.
