Trump claimed his campaign had zero contacts with Russia and no business deals in Russia. Turns out his campaign had hundreds of contacts with Russia and Trump was planning to build a tower in Moscow with a penthouse gift for Vladimir Putin. Source: Volume 1 of the Mueller Report

Trump's son, son in law, and campaign manager met with a convicted Russian spy at Trump's house to discuss a trade of damaging information on Hillary Clinton in return to relaxed relations between the two nations in the form of repeal of the Magnitsky Act. Trump lied that this ever happened and tried to create a cover story which was blown apart. Source: Volume 1 of the Mueller Report

Russian interference in the 2016 election was “sweeping and systemic.” Major attack avenues included a social media “information warfare” campaign that “favored” candidate Trump and the hacking of Clinton campaign-related databases and release of stolen materials through Russian-created entities and Wikileaks. Russia also targeted databases in many states related to administering elections gaining access to information for millions of registered voters Source: Volume 1 of the Mueller Report

The Mueller team was unable to establish a before-the-fact criminal conspiracy between the Trump campaign and Russia. The Mueller report includes a whole second chapter dealing with obstruction from the President and his allies, which included lying (by the President himself), witness tampering, interfering with principle investigators, and destroying evidence.

And what did Democrats do with all of this? Did they storm the capital? Did they even impeach the President for any of this? There was literally no response what. so. ever.

Oh, and during all of this the President promised pardons for those who would obstruct the investigation, such as Paul Manafort, who was literally meeting with a Russian Intel Officer and handing him Trump campaign data. If that is not collusion, what is? And then Trump pardoned him. So more obstruction on top of it all.
