I'm not yet convinced that accepting politically useful information from a foreign power would constitute a crime. It's certainly not good and perhaps we need to better legislate this area of election law. But it doesn't strike me as the level of coordination needed to make a conspiracy charge. Think of it like drugs...is this an illegal drug and accepting it constitutes a crime, no matter what? Or is it a legal prescription drug, meaning that you can get it legally (from a domestic source) but not illegally (from a foreign power)...or is it just tylenol and you can get it anywhere. The Russian government went above and beyond the distribution of information to the Trump campaign...that's not at issue. What is is whether there was sufficient coordination between that campaign or its people and a foreign power to constitute conspiracy to commit crimes in our electoral system. If the Trump campaign encouraged them or coordinated with them, then yes. If they knew something was going to happen and didn't report it, then yes. But just taking info? I don't think so.
Obstruction is a far more likely charge to come out of all of this and there's a lot more evidence of it.
