After the report was aired, it was immediately the subject of harsh criticism, especially when a key document could not be authenticated. As a result of the controversy over the use of the documents, CBS ordered an independent internal investigation. The panel in charge of investigation was composed of Dick Thornburgh, former governor of Pennsylvania and United States Attorney General in the George H. W. Bush administration, and Louis Boccardi, retired president and CEO of the Associated Press. The Thornburgh-Boccardi report said that some of Bush's former instructors or colleagues had told Mapes that Bush told them he wanted to go to Vietnam, but that he could not go because there were others ahead of him with more seniority.
