On December 21, 1970, Elvis Presley paid a visit to President Richard M. Nixon at the White House in Washington, D.C. The meeting was initiated by Presley, who wrote Nixon a six-page letter requesting a visit with the President and suggesting that he be made a "Federal Agent-at-Large" in the Bureau of Narcotics and Dangerous Drugs. The events leading up to and after the meeting are detailed in the documentation and photographs included here, which include Presley's handwritten letter, memoranda from Nixon staff and aides, and the thank-you note from Nixon for the gifts (including a Colt 45 pistol and family photos) that Presley brought with him to the Oval Office.
From The Nixon Prestley Meeting. (This site has comprehensive materials from this historic event including the note from Elvis to Nixon scribbled on an American Airlines notepad.)
I just came across this shot of Nixon and Reverend Moon (self-proclaimed messiah and founder of the Unification Church). Apparently Rev. Moon controls about 80% of the sushi-grade fish market.
