It seems obvious that the story broke now because someone who either has access to the inner workings of the CHRB, or who was provided access, decided to drop a dime to Drape. That's why Drape has emails, overage amounts, etc that aren't being disputed. You know, the basic way that coverups become uncovered.

Of course, the $64,000 question is who would do such a thing and what are his or her motivations?
