WASHINGTON (AP) — In an explosive allegation, a Georgia woman said Monday she and Herman Cain had a 13-year extramarital affair that lasted nearly until the former businessman announced his candidacy for the White House.

"Here we go again. I didn't do anything wrong," Cain said in a pre-emptive denial that lumped the accusation in with others of sexual harassment.

But the woman, Ginger White, said in an interview with Fox 5 in Atlanta that over the years, Cain paid for her airplane tickets so she could join him in different cities.

"It was fun," she said. "It was something that took me away from my humdrum life at the time. And it was exciting."
