I think it would be hard for anyone to disown their parents, they must believe he didn’t have sex with her, while you would hope they would be embarrassed by their parents begging money from Epstein (and publicly lying about ending friendships), I do understand why they would believe their father over a stranger.
What I do find strange is their silence about Epstein and Maxwell, who they both had contact with and accepted gifts from, they should have made some statement about the trafficking of minors for prostitution, particularly Eugenie.
@CathyorClaire thanks for that link, @Zippedydodah the charity funding looks to be quite opaque, hopefully there will be a spotlight on that in the near future, although it is chicken feed in comparison the the rest of the shenanigans.
