As long as he doesn't lie to the Feds, he should be OK.
Let's see what a dumb ass he is, shall we?
He is worth approx 2 billion.
He lied and risked jail over 750,000. That is .04% of his total worth.
That is 4 pennies per $100.
In my world - lets say I have $500, that is risking jail so not to lose $20.
He may be a billionaire, but he is a dumb ass.
