This is the letter that earned Elvis his badge for the Bureau of Narcotics and Dangerous Drugs. Now known as the DEA. The letter and the signature have been authenticated. These letters are an important piece of history as Elvis talks about his concern for our country because of hippies and drugs. In the handwritten letter, that he wrote mid-flight on American Airlines stationary, he is introducing himself to the president through then-Senator George Murphy. On the fax cover page, Elvis lists all of his contact phone numbers where he will be staying at the Washington Hotel under the name Jon Burrows. It is common knowledge that Elvis visited Nixon in the White House, showing up unannounced.
