To answer your question simply, yes, I do find that odd, and I find it concerning. I will say that one thing he was aware of was a plan to consolidate some of the contracts we had on that project team, so there was a risk that his contracted work would end. That may have factored into his choice to become a public servant.
Iif he truly was making the amount of money through his business dealings that we now think he was, through the markups, etc., it is hard to comprehend how that math works for him as an employee, unless he was able to do his other business at night and on weekends and this just offered some steady income. The math is questionable, for sure.
