AP Text: John Edwards' mistress tells Oprah Winfrey the former presidential candidate's wife didn't know about their involvement until after Edwards gave an interview to ABC News correspondent Bob Woodruff admitting the affair.
In quotes provided Wednesday by Harpo Productions, Rielle (ree-EHL') Hunter says John Edwards "came clean with" Elizabeth Edwards after the August 2008 interview. Hunter tells Winfrey people who "knew the truth" asked John Edwards not to do the interview. Hunter says Elizabeth Edwards "really wanted him to do that interview," but "she didn't know the truth."
Hunter is to appear on Thursday's episode of "The Oprah Winfrey Show."
John Edwards admitted in January he and Hunter have a 2-year-old daughter. He and Elizabeth Edwards are now separated.
