A source told The National Enquirer: "Elizabeth wanted to exact final revenge against John for destroying their 33-year marriage and their family by cheating with Rielle."
"On the secret video, Elizabeth spells out everything she knew about John’s affair with Rielle and how he managed to cover it up for so long."
It is not the first time Edwards has punished her cheating husband from beyond the grave, after she cut him out of her will which was signed six days before she lost her battle to breast cancer.
Her husbsand faces six counts, including conspiracy, four counts of illegal campaign contributions and one count of false statements.
