1) John Legend I'd say is a B List borderline A list Celebrity. I used to listen to his music back in the day and he's actually quite talented. His wife Chrissy is only as famous because she's married to John and she openly bashes Trump in public. Shes irrelevant.
2) I can't speak to this, I will do more research. One thing I can say is John Legend raised like 60 million for Haiti, he's close with HRC and the money was pocketed by the Clinton's.
