>The only thing the muller report found was trump obstructed the investigation, it completely exonerated any supposed connections to russia.
It did not exonerate him, quite explicitly. [1] The report found a lot of evidence of trump team making contact with Russians. You say yourself that the investigation was obstructed.
There was also this indictment on co-ordinated Russian funded interference in NA pundit/social media space. [2] Not to mention similar groups (I'm not sure about the status of the investigation in [2] at this point) have already been dismissed [3].
