As a completely unsurprising fact of life, Billy Carter was known for drinking beer, and got paid quite well to lend his name to a brand of beer during Jimmy Carter's presidency, because a few folks thought they could make a buck off of it.

There is not a shred of evidence that Joe Biden ever lifted a finger in his official capacity as a consequence of whatever business other members of his family had been up to, or that he had anything to do with whatever business they were conducting - including with persons who may have thought it worthwhile to curry favor with some member of his extended family.
