A man who once claimed he fathered the child of John Edwards' mistress now says in a book proposal that the former presidential candidate is the baby's father.
The New York Times reported Saturday that Edwards asked his campaign finance chairman to hide the paternity of Rielle Hunter's child.
The claims are in a book proposal by former Edwards aide Andrew Young.
The newspaper reports Young wrote that Edwards told Hunter they would marry after Edwards' wife died. His wife, Elizabeth, has cancer.
Edwards has denied he fathered the child. He has acknowledged federal investigators are looking into his campaign funds.
Hunter's attorney and a spokeswoman for Edwards each declined comment Saturday. A lawyer for Young did not immediately return messages.
