I'm so old that I remember when BMM was deservedly nicknamed the Clinton News Network. Except for admissions-against-interest - stories that cross a Lib/Prog narrative or claim - I avoid BMM.
My understanding, at this point, is that the "investigation" of Cuomo incidentally exposed Zucker's undisclosed relationship with a VP. The problem leading to his resignation was not the relationship per se, but that he didn't disclose it as it was beginning. IOW, a violation of CNN's sexual harassment policies, not any sort of contractual morals clause (who expects moral behavior among the MSM, anyway?).
