Lol, Biden isn't worried. He could pardon himself and/or Hunter. Matter of fact, there might be precedent for presidential pardon of people convicted of crimes in which the President himself is associated.
My only question in all this is: Why in the hell is Joe Biden not screaming constantly about witch hunts and deep states, lamenting his personal persecution, crying over his victimhood, casting vile public insults to all his enemies and promising absolute retribution? Why? Is he soft? Is he a pushover?
