James O'Keefe, does not have a very good reputation Bliss,
http://money.cnn.com/2017/02/22/media/james-okeefe-cnn/index.html, he has been convicted of misdemeanor crimes and is currently under probation, has been forced to pay $100,000 in a lawsuit settlement, has been accused (not convicted) of sexual assault, and has very low credibility. All of that is not to say that it's impossible for him to produce real information, and break real news, but again, not the most credible source.
CNN parted ways with Brazile, most mainstream news outlets pay partisan talking heads for their contributions.
Lastly, of course CNN and other outlets are focusing on Russia, it *could* be a huge, criminal charges, impeachment, removal from office issue, thats going to get ratings for sure. We agree, that so far there has been no concrete proof presented, we must all wait for the Mueller investigation to finish, and then, hopefully we will have more information to review.
What I see in your links is what I have always said, there is always "spin" in the media, for both liberals and conservatives, which is why it is so important to be able to look at both sides, read between the lines, and discern the truth. Writing off one side or the other as "fake news" puts you in the pocket of, and vulnerable to only one side of the story.
