The bottom line is that CNN and the MSM as a whole really are just the propaganda wing of the DNC. I know that claim gets generally written off as Fox News/Tea Party/conspiracy theory BS, but it's true and CNN has gone so far this time that they've actually verified it to be true. Not that we needed any more verification after Trump's "upset" victory, but it's absolutely true.
That's not to say that the DNC has direct oversight of the MSM, just that the MSM as a whole is made up of people who primarily support and parrot the DNC and skew everything they do to those ends. Some of it is intentional, some is probably subconscious, but it's very obvious to any impartial observer.
I was seeing headlines that suggested that they're probably doing that with the AT&T merger as the higher ups are pro-Trump. Not 100% sure because I haven't been following that story, but that's what the headlines suggested
