Raleigh, North Carolina, news station WRAL reports that former Senator John Edwards is preparing to admit that the 18-month-old daughter of former mistress Rielle Hunter is his child. In August 2008, Edwards acknowledged that he had an affair with Hunter, but denied fathering Frances Hunter, whom he claimed was conceived after the end of his affair. Edwards' longtime aide Andrew Young initially claimed to be the father, but in June reports surfaced that Young was shopping a tell-all memoir pinning the paternity back on Edwards. A federal grand jury is investigating whether Edwards' campaign illegally paid Hunter to stay silent about the affair. WRAL reports that Edwards' public admission could occur before the end of the criminal investigation. Frances' birth certificate names no father.
