I find this release disturbing.
The “leaks” we’ve further south in the investigation headed up by Mueller have all been plausibly ascribed to anyone with knowledge of the matters at hand and not on the investigating team. For example, the questions that Mueller allegedly wanted to ask Trump, which were characterized in the media as some sort of work product from the Special Counsel, when they actually ended up being prep material produced by Trump’s attorneys after conversations with the Special Counsel.
This, however, is source evidence. It would have had to come either from Cohen’s team, or from someone on Trump’s team who had access to it during the time when the common defense agreement was in force, or from federal sources in the Southern District of New York.
