Kennedy in a new memoir—"Once Upon a Secret: My Affair With President John F. Kennedy and Its Aftermath"— and an exclusive interview with Meredith Vieira for NBC's "Rock Center With Brian Williams" airing Wednesday.

Alford claims the 18-month affair began in 1962, when she 19 and interning at the White House press office. In the interview, she tells Vieira tha, as she lost her virginity to the president, she felt "overpowered," if not physically: "I think overpowered in the sense that he was the president -- he was this unbelievably handsome man, 45 years old -- overpowered in the fact that he had chosen me," she explains.

In her memoir, Alford says she met Kennedy while swimming in the White House pool. He later led her on a private tour of the White House, ending in the first lady's bedroom, where the affair began. Alford also claims that she had sex with the president days before he was assassinated.

Alford's alleged affair has been in the news before. Though she wasn't named in Robert Dallek's 2003 biography of Kennedy, "An Unfinished Life," a short passage in the book mentioned that the president had had an affair with an intern. The NY Daily News identified Alford, and she confirmed the relationship in a statement.
