There’s no evidence at all, based on these documents, that it had anything to do with Don, Jr., the Voronina meeting or anything that has to do with the campaign at all. Even if it did, who cares? Jared and Don, Jr., took a meeting that everyone immediately regretted and did nothing, at all, based on said meeting? I think Mueller would love nothing more than to send Trump’s family members to jail, sure, but what, exactly, would that prove? Other than that he’s a corrupt prosecutor? All that Flynn pled guilty to were process crimes. The fact that he’s been used in this way to, essentially, keep himself from being pauperized and keep his son from being prosecuted all for nothing that has ANYTHING to do with “collusion,” which is ill-defined anyway... this is just pretty appalling that it can happen in our country.
Mueller isn't going to charge hin with meeting, but with lying to Congress about it. He will say (falsely) that the meeting was about Trump Tower Moscow when the Don Jr testified to Congress that Trump Tower Moscow had died earlier in the year
