Putting this all together, all three news channels have shifted their coverage away from obstruction and collusion over this past week, even MSNBC. CNN and Fox News have largely ramped down even their coverage of Mueller, but MSNBC appears to be trying to keep the story alive for as long as it can.
In contrast, the web-searching public seems to be largely done with all three stories.
In the end, it seems that with the exception of MSNBC, the Mueller story is finally over for both television news and the public. The only question is how much longer MSNBC will try to keep the story alive.
