Don't be silly. He is a rich white guy. Prison would inconvenience him. Think about how it would affect his life. I'm guessing that house arrest, every other weekend, is the most that he would get for any crime imaginable.
Any
federal crime? you may be right, but that's not current reality. Remember NY? Our AG is looking at the Trump Org and anything which ties to that or any other activity that our state has jurisdiction over are being probed and that means shell corporations won't be recognized as a means of escape wherever they may be. If it ties back to NY, NY can seize it if there is criminality, even dissolve Trump's empire and take every cent. Then he'll be a broke ass white guy who will still owe millions or more in debt that he likely won't be able to deduct or go bankrupt over, and THEN we come to criminal consequences. No help from the Republicans. No protection from the office and "gofundme" to get a lawyer. Even his pension can be garnished if the courts wish although they may allow him some portion, perhaps media wage.
We also have laws about profiting from crimes so books? Yes please! Paid interviews? Absolutely. All donations gratefully accepted.
Maybe he'll only get a few years before parole, but no pardon, no money, and only rage at the four walls. S
Courts could deem him a public menace and a potential threat to state security and so communications cut off or curtailed, no interviews to pass on potentially coded messages or to foster rebellion, and isolation for his protection. The Secret Service can bring him burgers and KFC and sit on a stool outside his cell.
