Most of the claims of Russian influence were directly proven, the only thing not proven was direct coordination with the presidents campaign. Notably, there were several ‘dangled pardons’ to prevent people from testifying (pardons that were eventually granted) so who knows what actually happened.
I think the most dangerous claims about Russian interference could not be proven true, they weren't proven false. I'm talking here about Trump being a full on Russian asset.
As a side note, I'm not sure that he is _explicitely_ in contact with Russia, but since he got oRussian assistance, an implicit quit-pro-quo is obvious to me.
The fact Russia meddled in US elections is pretty clear cut by this point.
