The forgery allegations subsequently came to the attention of the mainstream media, especially after experts also questioned the documents' authenticity and lack of a chain of custody. The original documents have never been submitted for authentication. The man who delivered the copies, Lt. Col. Bill Burkett, a former officer in the Texas Army National Guard and outspoken Bush critic, claimed that he burned the originals. Burkett admitted lying to CBS and "USA Today" about where he had obtained the papers and eventually expressed doubts of his own about their authenticity.
