*Understand* why Barr, Trump, and Graham are lying about the Report concluding that there was no collusion, when the Report never adressed that: they're concerned that, in the future, evidence of collusive crimes will be revealed, and they want to say it was already investigated.
(2 of 2) Here's the truth: Mueller investigated a narrow vein within the federal conspiracy statute and a narrow vein within the illegal solicitation of foreign campaign donations statute. His review was so narrow that even these federal statutes could come back in play later on.
PS/ In other words, Mueller looked at two federal statutes in particular with respect to a narrow set of facts within a much larger story that involves many more nations, events, and courses of conduct to be investigated than the ones involving the Russian government he wrote of.
