Hensley met John McCain in April 1979 at a military reception in Honolulu, Hawaii. He was the U.S. Navy liaison officer to the United States Senate, and was accompanying a group of senators heading for China. She was in Hawaii on a family vacation with her parents. Hensely was talking to Jill Biden, the wife of Senator Joe Biden, who suggested that she talk to McCain; her father made the introduction. He was almost 18 years her senior; by her later description, each fudged the age they said they were to the other: "He made himself younger, and I made myself older, of course."
