Report: Liz Edwards Wouldn't Want Kids with John

CBS News reports:

Elizabeth Edwards reportedly doesn't want her estranged husband, former presidential hopeful John Edwards, to raise their kids if she loses her battle with cancer.

But can a mother legally keep an estranged spouse from getting custody in that kind of situation?

CBS News correspondent Elaine Quijano reported Elizabeth is looking into whether the couple's 28-year-old daughter, Cate, can assume legal guardianship over their two youngest children, Jack and Emma. The New York Daily News reports that, if she dies from the breast cancer she's fighting, she doesn't want them raised by John.

Elizabeth's sister told the paper: "There a lot of family members who are willing and able" to take care of 10-year-old Jack and Emma, now 12.
