MUSKOGEE, Oklahoma - The adoptive parents of a Native American girl from Oklahoma sat down with Dr. Phil Thursday to discuss their petition to the U.S. Supreme Court and the contentious adoption case.

The girl's father, who is from Muskogee and is a member of the Cherokee Nation, used the Indian Child Welfare Act to get custody of his two-year-old biological daughter, Veronica.

The South Carolina couple, who adopted her and raised her since birth, Matt and Melanie Capobianco, are fighting it.

They say having her taken away has torn their family apart.

Dr. Phil sat down with the Capobiancos, as well as the Assistant Attorney General for the Cherokee Nation and a tribal judge, who is familiar with the Indian Child Welfare Act.

"You want to commit cultural genocide, steal a people's children and taken them away and place them in non-Indian homes. This is what was happening before this law was enacted," said tribal judge Les Marston.
