I love stuff like "sketchy meetings on the tarmac" - nothing screams partisan hackery & conspiracy theorist like that one.
And what do we KNOW right now? Investigation over, and no indictments. So, for all of your & Trump's year+ innuendo and "worse than Watergate" talk, it amounted to a big fat nothing.
I can list the same partisan hack stuff as you about Trump - Manafort's past w/ Russia, Russia's known hacking, Trump telling Russia to find the missing emails. You won't think so, because you're immersed in koolaid, but it's the same as what you listed. And it might not amount to a hill of beans - but they're investigating it, and it's not because "lefties" pressured them into it. There was enough there there to warrant an investigation.
And you seem to think the investigation continues just because "lefties" are demanding it. Clearly, it makes you extremely uncomfortable that they're investigating - but you're going to have to deal. They're not going to call it off at this point. Just sit tight & see what they come up with.
