RALEIGH, N.C. -- It is beginning to look like the blank space on the birth certificate where the father's name is supposed to go might never be filled in, as speculation over the paternity of Rielle Hunter's baby continued Saturday. Hunter issued a statement through her attorney saying she would not submit her daughter a genetic test to determine the father of the girl born to her in February.

That came a day after former North Carolina Sen. John Edwards admitted to ABC News that he had had an affair with Hunter. But he vehemently denied that he got her pregnant, and he said he is willing to take a paternity test to prove it. He said their affair ended in 2006, before she would have become pregnant.

Efforts to reach Edwards on Saturday were unsuccessful.

Hunter and a former Edwards campaign aide, Andrew Aldridge Young, posted statements online in December saying that Young was the baby's father.

But on Saturday, ABC News reported that Hunter's sister, identified only as Melissa, challenged Edwards to take a DNA test, saying, "Somebody must stand up for my sister."
