See the details behind the guilty plea at Diplopundit's post, here. The bottom line is that $60,000, which DOJ's press release described as "lucrative kickbacks," went from an OBO construction contractor to an OBO employee in exchange for insider information that gave the contractor an advantage in winning contract awards.
The guilty party in this case is someone I like and have high regard for. Her motive was financial desperation, apparently. Considered on a scale of culpability, her offense ought to be seen as somewhat less than that of the contractor who purposefully cultivated her as his inside source.
Now, as for the real villain in the piece, OBO's construction contractor Montage Inc and its CEO, I have always had as low an opinion as one could have, right from the start of its engagement with OBO and many other government clients. There was just an auru of sleeze around whatever I saw of the company.
Good riddence to that guy.
