The OAG has not made a recommendation. This is because they expect to get testimony in a certain way following certain lines. If this is done, they will be inclined to recommend leniency.
Specifically, C & S will be asked, when then they testify, if a quid pro quo was made. The "deal" such as it is, will require them to say "no," as strange as that sounds.
This is shaky ground for them, but if they have good attorneys, and they do, they have worked out some other way to outline an agreement that doesn't quite constitute quid pro quo, but also manages to offer enough confidence that their lawyers are OK with it.
Happens every day.
