What is your theory of a crime here? Even in your worst case scenario all that Joe did was use his influence to get Hunter a job, and that's almost certainly a stretch--presumable the entities involved knew who Hunter Biden was and didn't require any intervention from his father to give him a job.
The thing is, this is the most common form of legal graft in Washington, or are you so naive that you don't realize this is the normal for the entire political/media class, Republican or Democrat?
This is literally just throwing shit against the wall and hoping it sticks. It's pathetic, and you show absolutely no concern at all for the grifting, criming, and grafting by the Trump family. As has been said repeatedly around here, look at the Trump payoffs to porn star Stormy Daniels, the Trump charity, Trump University, the siphoning off from campaign contributors and tax payers to Trump and Trump properties, the probable foreign bribes to the Trump family through their properties--that sale of 666 in particular by Jared looks really shady, the attempt to bribe Ukraine with tax payer money--it's an endless list.
