This is what I've been arguing since 2017—and laid out in my 2018 book Proof of Collusion. Aiding and Abetting is a collusive crime, impeachable, and not an offense the Mueller Report considered.
Perhaps if we'd been having this conversation all along, as we should have been, my phone's autocorrect would've known what I was typing as I typed it.
1. Bribery
2. Money Laundering
3. Aiding and Abetting
4. "Compromised"
You can see for yourself how often those terms (all about "collusion") appear in the Mueller Report, as opposed to references to a conspiracy no one alleged.
