James Baker swore under oath that he had received the briefing book from William Casey, Reagan's campaign manager, but Casey, then campaign manager, later CIA director, vehemently denied this. David Stockman, the head of the Office of Management and Budget, admitted using the Carter material while helping Reagan prepare for the debate. Stockman said the documents obtained were just position papers, not in question-and-answer format. Frank Hodsoll, also a member of the debate team, said that they were in Q&A form. The investigation turned up hundreds of pages of documents from the Carter campaign in Stockman's files as well as in Reagan's campaign archives at Stanford University's Hoover Institute. One document, an itinerary for Carter during the week prior to Election Day, had "report from White House mole" written on it. This seemed to confirm author Laurence Barrett's conclusion in his book that the material had been stolen. But "U.S. News & World Report" indicated that the document in question had been volunteered by someone working for Carter. Other papers were turned in to "The Washington Post" by a collector of political memorabilia who, in October 1980, had exhumed them from a dumpster behind Reagan headquarters in Arlington, Virginia. The press speculated that the Reagan campaign had been concerned that Carter would pull an October surprise during the campaign—cutting a deal with the Ayatollah Khomeini for the release of the 52 hostages held for over a year by Iran, a bombshell that some believed might have sent Carter back to the White House for four more years. "Newsweek" wondered whether a clandestine operation involving ex-CIA agents had been undertaken by the Reagan team to keep close tabs on the Carter campaign. This was confirmed by "Time" in its July 25, 1983, issue. According to that report, William Casey brought in former agents of both the CIA and the FBI to gather information from colleagues who were still with that agency. Jimmy Carter complained that the pilfered documents revealed the "essence" of his campaign, implying that his reelection bid had been done great harm when they fell into Republican hands.
