I think they have it in there head that unless they shot at leat dozen or so election officials they really haven't broke any laws...Like you people care about the truth.
What Trump Jr wrote there is the active planning of breaking the law... It conspiring to break the law...
If you are caught on tape trying to plan a murder, you get tried for 'Conspiracy for Murder' even if no one is dead or even shot at..
Undermining elections is a crime even if you do it non violently, Conspiring to to do this crime is a crime as well..
There seems to be plenty of evidence of this people in the Trump Admin conspiring to commit this crime... Have they got Trump personally, I don't know, we haven't seen any major evidence as of yet (or I could missed it)...
