We need to talk about CNN and the Cuomo brothers — and not just their shared fascination with the N-word.

On Wednesday, following yet another appearance by New York Gov. Andrew Cuomo on his little brother’s CNN program, the network refused again to explain how it justifies what is, by all appearances, an ongoing lapse in editorial judgment. Put as simply as possible, it is unethical for a news network to allow one of its hosts to interview a guest who is both a family member and an elected official. The inherent conflicts of interest are clear.
