The Trump world is a horror show of corruption and un-American behavior. The Mueller report reinforced the truth of that.
Russia attacked our systems and attempted to interfere in our elections through a concentrated social media campaign.
Yet, people like Tucker Carlson encourage a softening toward our adversary and engage in propaganda in support of Russia.
Much of Russia's social media interference campaign had a (successful) focus on promoting Trump and dividing America.
Key Trump supporters actively engaged with the fake and bad faith social media interference from Russia via re-tweets and other amplifications.
We also know that the social media content promulgated via Russia found and finds an easy channel in the right-wing news coverage which ultimately ends up on this board, among many other places.
Russia also hacked Democratic Party and Clinton operations in an effort to bring Clinton down.
The Mueller investigation was unable to prove that Trump and his campaign co-organized those efforts (collusion), but Trump openly and actively welcomed those Russian efforts.
Don Jr. and others met with Russians looking for opportunities for Russian intelligence to smear the Clinton campaign. The intention is there, but those efforts largely proved fruitless (so no effective coordination/collusion).
Mueller waved off any coordination and collusion claim for lack of clear proof. Mueller did so despite extensive interactions between Russian actors and despite that Trump's team actively lied to and obstructed Mueller's investigation. Mueller's report acknowledges that there may indeed have been wrongful coordination and that the missing information could alter the conclusions.
Meanwhile, in no small part because of possible business advantages for Trump in Russian, Trump's campaign team was actively engaged with Russians and began talks about softening America's hard stance against Russia and watering down sanctions. (Not coincidentally, right-wing support for Russia over Ukraine and U.S. interests grows).
Mueller laid out in painstaking detail how Trump obstructed justice. That obstruction would amount to a crime. Indeed, he expressly concluded there was substantial evidence of the commission of wrongdoing. However, Mueller stated at the outset that the DOJ cannot indict a sitting president, so he lacked authority to reach the conclusion that Trump committed a crime. All he can do is lay out and assess the evidence. Basically, Mueller concluded that there was indeed a "1", there was another "1", and there was yet another "1", but he could not by law complete the sum and add 1 + 1 + 1. A different tribunal must do that math. Mueller was clear that by that inability he was not concluding that no crime was committed. That arcane and unfortunate failure to meet the system's needs rendered a massive disinformation campaign about just what exactly Mueller concluded.
