It is being reported that it was an as yet unnamed Republican opponent (or perhaps opponents) of Trump who first commissioned the dossier and that the Hillary campaign and DNC took over the funding after the Republican opponent was vanquished.

Fox reported that one name keeps coming up but they have not yet been able to verify which opponent started the fake opposition research project. Let's see, who was it that had all the big money and was supposed to be a pretty sure bet to face Hillary - and who, along with is family, supported Hillary after he was knocked out of the race?

I'm thinking it was "Low Energy" Bush, an establishment swamp dweller if ever there was one. If not, I would not doubt at all that it came from the snake Ted Cruz, who has been scheming to become President since before he took office as a Senator. It was his campaign that released the Melania "nude" photos and his campaign that falsely reported that Ben Carson was dropping out of the race at a critical caucus.
