Okay, so you've found one leftist article that attempts to claim that the entire laptop is not authenticated.  Most stories that come up when I search for this on Google or even Bing, are from the right.  So yeah, sure, I'll buy into them not reporting entirely accurately.  I don't trust the media, period.  Left, right, it makes no difference.
So, KF, is there an objective media outlet that has weighed in on this?
