Questioning an election is one thing. Intentionally spreading disinformation, and pressuring a VP to do unlawful activities to keep you in power is a different thing.
Disinformation is a retarded word. In this context “spreading disinformation” implies a nefarious motive, which, if he believes the election was stolen, he’s “spreading” what he thinks is the truth. There isn’t a law against being delusional.
Also, claiming what he did was unlawful also implies that what he asked the VP to do was a crime. His legal advisers told him the VP had the authority to do it. I don’t think he does have that authority. But the remedy for that is to challenge it in court. And Trump would have lost. And we’d still have the senile old pedophile in the White House that we have now.
