Preeminent among them was the chemical giant DuPont. Nader took readers to Rodney Square, in the heart of Wilmington. There was the ritzy Hotel du Pont, housed in a building owned by DuPont, next to a theater built by DuPont, connected to a bank controlled by the du Pont family, surrounded by law offices and brokerages—all affiliated in some way with what was known simply as “The Company.” The du Ponts owned the state’s two largest newspapers and employed a tenth of the state legislature. The governor was a former executive. The state’s member of Congress for most of the 1970s was Pierre Samuel du Pont IV.
I don't know why anybody would be shocked that Biden would appoint their representative to this transition team. Biden once owned the DuPont mansion for God's sake.
