I have read the Mueller report several times. I think you need to read this again:-

If a President obstructs an enquiry and refuses to answer questions and his own AG then says he hasn’t been exonerated, then he is lying when he claims he has been.
When the only reason any investigation cannot reach a legal conclusion is the non cooperation of key witnesses what conclusions can any reasonable observer draw? That there is likely to be a reason for the non cooperation or that those not cooperating are completely innocent? Smoke without fire is very, very unlikely.
I know my answer and a few very well placed others seem to agree with me.
To quote from the above:- “A statement signed by over 1,000 former federal prosecutors concluded that if any other American engaged in the same efforts to impede federal proceedings the way Trump did, they would
likely be indicted for multiple charges of obstruction of justice.”
Barr also ruled that a sitting President could not be prosecuted. So Trump was impeached instead, turning the process into political theatre rather than a pursuit of justice. He was cleared because of the requirements of a 2/3rds majority in the Senate, not by a jury of citizens assessing evidence. A few brave Republicans voting guilty says all any objective observer needs to see.
Russiagate was no hoax. That the US system failed to fully expose it doesn’t alter that.
Legally the verdict was “not proven”. In the court of public opinion it was. The Trump campaign, which Trump led, was guilty beyond any reasonable doubt.
