All Media Mistakes Are in One Direction, If You Ignore All of the Mistakes That Aren’t
By 
Greenwald asserts, in light of the retracted CNN story, that all the media’s mistakes on Trump and Russia advance an anti-Russia/Trump narrative:
But CNN is hardly alone when it comes to embarrassing retractions regarding Russia. Over and over, major U.S. media outlets have published claims about the Russia Threat that turned out to be completely false — always in the direction of exaggerating the threat and/or inventing incriminating links between Moscow and the Trump circle. In virtually all cases, those stories involved evidence-free assertions from anonymous sources that these media outlets uncritically treated as fact, only for it to be revealed that they were entirely false.
Hmmmmm. One of the CNN reporters responsible who left because of the retracted story is Eric Lichtblau. Now that you mention it, he did do some problematic reporting on Trump/Russia:
As we’ve discussed before, this was a Judy Miller-level botch. By October 31 it was definitely the consensus within the FBI that Russia’s interventions were intended to help Trump. Lichtblau just got played by the alt-right faction within the FBI. And what makes it even worse is the context — this false nothing-to-see-here story on Trump and Russia landed during the timeframe when the Times was running one A1 story after another about an actual non-scandal: redundant copies of emails that showed no illegal behavior on the part of Hillary Clinton being found on someone else’s laptop. Odd how Glenn “forgot” about a massively botched story that was more important than any of the ones he discusses.
And, of course, it wasn’t just this — Lichtblau was also responsible for one of the most ridiculous attempts to frame a story involving absolutely no objectionable behavior by anybody into a Clinton scandal because questions raised were casting troubling shadows. Needless to say, not only did Glenn see nothing problematic about this, he was doing the exactly same thing himself.
The media makes lots of mistakes. I think this is important — indeed, I even think it’s a more urgent subject than the campaign tactics of someone who well never run for president again. But the idea that they’re all in one direction is silly. It’s just that when the media errs in a pro-Trump and/or anti-Clinton direction Glenn doesn’t give a shit.
