Greta Give Open Invitation to Rita Cosby

I visited Greta's site today (http://www.foxnews.com/ontherecord/index.html) and she had the following statement posted

"Rita Cosby has an open invitation to appear on the show to answer allegations others have lobbed at her"

I personally think that if Rita Cosby were smart she would try to just dissappear like Donna Hogan did. Her ship seems to be sinking.
