Yes, Elvis Presley met Richard Nixon on December 21, 1970 — to the shock of just about everyone working at the White House at the time. The King of Rock 'n' Roll descended upon Washington, D.C. in the hopes of securing a badge from the Federal Bureau of Narcotics and Dangerous Drugs.
Nixon obliged, giving him an "honorary" badge that didn't actually hold any power, and Presley declared his full support of Nixon's presidency.
