I thought this already happened. And he wasn’t the sperm donor. A father is who raised you. Someone who screwed your mom once is a sperm donor. And old Bill told his victims he didn’t have any sperm, anyway. They had to borrow some from Hillary’s law partner (sadly, only the less handsome one provided any) to make their campaign gimmick, Chelsea, appear.
This was tested while BC was in the White House. I didn’t pay close attention to the details, but I suppose the question is whether the test was performed by an independent, trustworthy partner. Not that Bill would ever cheat about something like that.
I had heard that story before too- when first told that ‘Danny’ was his so he replied that he couldn’t be, because he had the mumps when he was little so he was sterile.
There was no reliable chain of custody of Bill’s seed(s).
It would be simpler to check for playground drool of one of Chelsea’s kids, but if Web’s their bio -gramps, that’s no help.
