Trump got away with it- his interpretive conclusion of the Mueller Report. So, according to him, and his experience, it's not illegal, and he can do it again. And again. He's right and everyone else is wrong. His base is right with him. He's right and the FBI is wrong. Why is the FBI wrong? They're corrupted by Democrats.
The real danger here is normalizing this attitude and belief. Spreading these lies so people believe this is how it is. That Trump speaks a truth nobody else will. His base sees this as "winning." Trump wins again.
It is clear neither he, nor his base appear to have even the most basic grounding of knowledge and information about American civics and government. It isn't what the law says. It's what they say... or rather what he says, with which they agree.
