I find it very interesting.  I believe Barr is just summarizing the Mueller report.  But, Barr seems to indicate that Guiccifer 2.0 (fake Guiccifer) is a Russian GRU asset.     That has some major implications in my opinion.  If correct, it suggests that Russian intelligence was trying to frame Russia (by using fake Guiccifer 2.0) in order to claim responsibility for a hack!  Now why would they do that? ...     Edit- Or is this step one in exposing how the CIA can use its technology to  mimic foreign hacks...?
