Let it go.
If your father did obscene things to a fat chick with a cigar, would you throw him under the bus?
No, neither would I.
LOL!
Under those facts, I would not have put myself in such a defacto endorsement position.
The only sympathy one should have for Chelsea is that she had such cretins as parents. She's an educated grown woman, however, and making her own choices now.
My dad did not do obscene things to a fat chick with a cigar. He worked very hard for his family, stayed faithful in marriage and served his nation honorably during Korea and Vietnam. A cowardly cad like Bill Clinton couldn't have shined my father's shoes.
