From what bits and snips I’ve run into, and can sort of recall, the dossier was collected from various places. Even read that the salacious/peeing on the bed stuff was written as a joke on one of the chans and was picked up and put in there.
So I really have no clue.
I think this is worth a dig on this. I am looking through the interwebs to trying to find some origin of the Steele dossier. I seem to recall a report that the story line (Russian prostitutes peeing, etc.) was actually from a story concocted much earlier to be used against yet another Republican. Am I mis-remembering this or do other FReeQs recall this? Maybe it was a joke posted all the way back in the 4chan days....
