MISTRESS' FAMILY SUGGEST THAT EDWARDS TAKE DNA TEST

The sister of the woman that John Edwards slept with and supposedly had a baby with is, thinks that John Edwards should take the DNA test and that she is tired of everyone saying mean things about her sister.
First of all she slept with a married man who's wife is sick with cancer. I do not think she is innocent. I am sorry but I do not understand women who sleep with other women's men. They just prefer to be used.
There is a child involved a six month old baby girl. John needs to get those test and prove the baby is or is not his. That child turns out to be his. I hope he will be a part of that baby's life. The baby is innocent.
