Writing at PJ Media, Matt Margolis cites a fund raising letter sent out over the signature of "Dr." Jill Biden, and the "attack" she mentions is the report on Joe's mishandling of classified material authored by Robert Hur.
I hope you can imagine how it felt to read that attack -- not just as Joe's wife, but as Beau's mother. I don't know what this Special Counsel was trying to achieve.
Except of course Jill Biden was not Beau's mother. Joe's first wife, who died in a car accident, was Beau's mother. The entire Biden clan seems unacquainted with the concept of "truth."
