Jody Wilson-Raybould is many things but she is not an idiot and she will have recognized that the PMO was willing to spin and possibly lie to get its way. Whether on SNC-Lavalin or SCC appointments or any other file it took an interest in. I have to bet she had a smart phone.
The transcripts will be interesting however the raw recordings where they exist will be much more interesting simply because “tone” is important in the sorts of conversations Ms. Wilson-Raybould recorded. One snippet of Justin yelling at her and he’s done.
