WASHINGTON (CNN) - John Edwards supported his wife writing about their marital problems in the wake of his affair with a campaign staffer, the former presidential candidate said in a rare on-camera interview airing Thursday.
In the brief television interview with talk-show host Oprah Winfrey, Edwards said he never suggested his wife, Elizabeth, change any part of the book, even chapters that described the most personal details of her reaction to his infidelity.
"I think it's how she feels, it's what's inside of her," Edwards said. It was his first television interview since publicly acknowledging the affair nine months ago.
Among the revelations in her book out this week, Mrs. Edwards said she became nauseous when her husband told her of an affair with Rielle Hunter in 2006, who was hired to make Web videos about Edwards as he geared up for his second presidential run.
“I cried and screamed,” Mrs. Edwards writes in the book. “I went to the bathroom and threw up." Mrs. Edwards added that she urged her husband not to run for president in order to protect the family if the affair became public.
In the interview with Oprah, John Edwards said he wasn't sure whether his wife would leave him after he admitted to the affair.
"I didn't know, I think the honest truth is that I didn't know what she would do," he said.
“I don't think anybody knows when they go through something like this."
Edwards also said he and his wife are "are getting to a good place." But he added, "It's not over."
John Edwards currently faces a federal investigation over the $114,000 in payments to Hunter's production company. Edwards denies any wrongdoing in how Hunter was compensated.
