In The Smithsonian, Peter Carlson recounts the famous 1970 meeting between RN and Elvis Presley.  He quotes Egil Krogh’s notes:

“I’m on your side,” Elvis told Nixon, adding that he’d been studying the drug culture and Communist brainwashing. Then he asked the president for a badge from the Bureau of Narcotics and Dangerous Drugs.

“Can we get him a badge?” Nixon asked Krogh.

Krogh said he could, and Nixon ordered it done.

Elvis was ecstatic. “In a surprising, spontaneous gesture,” Krogh wrote, Elvis “put his left arm around the President and hugged him.”
