Most likely the document came from Bleak. BHS said he talked to Bleak and was expecting documents to prove his claims. If this is true then it's been in his hands for less than a week. Also remember that Thefuturetrump said he talked with Bleak as well but couldn't get the documentation since Bleak had to pass it through his lawyer first. Perhaps Mr. Bleak screwed the proverbial pooch on this one and released info he shouldn't have.
Doesn't matter, it's out now. Hopefully we'll see some PR Monday explaining it so it's no longer limited release.
