Quick note: Barr lies

Barr certainly lied in a very material way in the press conference when he said "no evidence":

the Special Counsel’s report did not find any evidence that members of the Trump campaign or anyone associated with the campaign conspired or coordinated with the Russian government in its hacking operations. In other words, there was no evidence of Trump campaign “collusion” with the Russian government’s hacking.

Rather, as I and others have been explaining since the four-page letter came out a month ago, there may not have been enough evidence, but there was definitely some. This is confirmed in the first-volume executive summary:

p. 9

Especially since the insufficiency is tied to ongoing investigations (the redacted matter, evidently related to Gates and Stone) and to false testimony (by Flynn, Papadopoulos, etc.), or evidence that was destroyed or otherwise denied to the investigators

p. 10

They might have had sufficient evidence if the report had been delayed until the investigation of Gates and Stone was finished, and/or if suspects hadn't withheld it or concealed it in one way and another. (Or I'm totally convinced they would have; it's way too much evidence to ignore.)
