Trump claims in writing and under penalty of perjury that he had no business dealings with Russians after he became President, and then has Cohen admit in court that he did

I don;t think that is what was claimed. June 2016 is during campaign. Mr trump lied about his business to reporters and his supporters. So what. His supporters don't care (and I suspect they love the fact he lies) and reporters file charges for lying.

Other people may be liable for their testimony before Congress but I am sure the Trump family all have pardons good to go.

The day he leaves office

I don;t give a flying frak about what happens to him AFTER he leaves office. I am not trying to get revenge. I want to protect America from what he is doing to it.
