Precedent?
John Edwards was prosecuted for similar crimes. Spiro Agnew was prosecuted for taking bribes. Aaron Burr was prosecuted for murder.
What is unprecedented here is the string of criminal behavior by Donald Trump. The reality is that the American people (well, a minority of the voting public, but enough, given the Electoral College) elected a known career criminal to the Presidency. Trump was a conman and, simply, a crook, before he sought public office - and this was common knowledge.
The fact that 60 million-plus Americans will happily vote for a career criminal... well, it's mind-boggling, but there it is.
Bull. The federal government (Donald Trump's Department of Justice) prosecuted and incarcerated Michael Cohen for being Trump's bag man. That kind of suggests that they detected a crime. They didn't prosecute Trump because: 1) he was in the White House; and 2) a crooked Attorney General forbade it. That's a world different from "determining there was no crime. Try to get it right, or stop spreading falsehoods.
Well, I suspect that Trump's attorneys are going to fail that test, Aquapong. And I'm going to take a wild guess that you've never spent a year as a law student.
