Nobody is mentioning or even suggesting Bill having a part in this. You just know he’s as deep as she is in this.
I suspect his involvement is only with raising money and making deals for their foundation, Hillary receives the money and handles all the dirty work He is probably like a lot of husbands who leave the book work to their wives. He is as big a liar as she, but I don't think he even know when she is telling a truth or not. He was never the brains behind all the schemes and lies to cover, give or take a few dead bodies over the years.
Where I think he is involved: He may be leaking her to the authorities, to finally be rid of her. She needs to be watching her own back door more closely. He's dodged enough ASHTRAYS in his lifetime.
