I'm not really sure that there was collusion between the Trump posse and the Russians. If there was, it was unwittingly, as he and his posse are witless to begin with.
I suspect that the coverup is all about money laundering for the Russians. That is what they are trying to coverup. Which is the whole reason why Trump is trying to get along with Russia better. They've got the goods on him. As does Flynn.
Whatever it really is that they are trying to coverup, it's going to come out, and sooner than later. I fully expect jail time for Paige, Manafort, Flynn, Kushner, Sessions, and the others that are involved, including Trump at the end, and including his current lawyer, who is a complete idiot I think, btw, since he's no longer in NYC, he's in DC, where you can throw a dime and hit a lawyer anywhere you go.
I think people are talking about the wrong there there, but there is a there there, and Trump is afraid of what will happen when that there actually is.
In other words, what we are liable to find out is worse than collusion, it's going to be iron bracelets for Trump's whole family.
Let's face it. He didn't expect to win. Now that he has, he thinks he's won the dictatorship. He didn't win that, he won President. And it's something that he doesn't understand. And since he's uneducable, he never will.
