has it not occurred to you that this type of skim is what happens with nearly every bill passed that involves large sums of money?
The cleanest wy is stock tips, but it can be land use gifts, flying perks & vacays (sure! bring the fam, Senator), - most anything.
This type of graft is 100% SOP for government employees. Our mayor just hired his nephew to run public works in our little town of 6000 people - for $195K/yr and used the "he's not on the payroll, he's a contract hire" line.
Same thing with guys working as an ":ACTING" government official - they are temps and make pretty decent bank for temps.
I imagine guys like Grenell make really big bank
