DuPont essentially owns Delaware so no surprise they are tied in with the Biden fam.
On another note, I did some contract work for DuPont back in the day. It was an unusual experience to say the least. Anywho, apparently they have a select number of higher ups in the organization that are classified as "friends of DuPont". These "friends" are essentially untouchable, or so I was told. Makes anon wonder just what one would have to do to earn that title? No telling.
