It's not hard to imagine that Boeing felt uncomfortable at being challenged by MDH over the Little Bird contract.
Whether this has advanced the uncovering of the recruitment of a former Army purchasing officer we shall have to see. However, even if Tilton offered Col. Vergez a $3m annual salary (and I'm not saying she did) this in itself will not indict her.
It is only if it can be proved that either, a). Prior to leaving the US Army Col. Vergez influenced the decision to go with MDH or b). Subsequent to leaving he, or other parties representing MDH's interests, were instrumental in swinging a decision in favour of MDH, that any prosecuting could be done.
The US Military tender awards process is not the cleanest of rituals but aside from Tilton recruiting what might be referred to as a sort of "insider process trader" (ie. someone with intimate knowledge of the tender awards process), which in itself is no crime and something practiced by several vendors, I don't see why MDH would need to twist any arms, so to speak.
Was their Little Bird offer not distinctly cheaper than Boeings?
