Good. Don’t get ahead of me.
#3 What can YOU conclude about the origins of the dossier?
Your partial answer, above, is noted.
Hard to say, for sure. My best guess would be that it STARTED as opposition research, done by Republicans who wanted dirt on Trump. Hillary picked up what was started, and then added funding to the effort. I think much of the information was supplied from Russian intelligence. Ironic, that Hillary was in collusion with the Russians, not Trump.
