John Edwards' legal troubles are over, but the sex scandal that ended his political career will be back in the spotlight soon. His former mistress Rielle Hunter begins a publicity blitz next week for her tell-all book, What Really Happened: John Edwards, Our Daughter, and Me, with an appearance June 22 on ABC News' 20/20. In an interview with Chris Cuomo, she "speaks candidly about her current relationship" with Edwards, his relationship with their daughter Quinn and what she would have said had she been called as a witness in Edwards' recent corruption trial, the network says in a news release.
