First, who gave Brennan the dossier?
Second, was he aware that the information was paid political fodder intended to damage the opposing party’s candidate? Or, as no fan of Trump himself, did he even care?
Lastly, it appears that Democrats were willing to use their contacts within the Deep State to accomplish their mission to smear Trump. It raises the question: Was Brennan aware that he might have been used as a tool of the DNC in infusing the document into the bloodstream of the intelligence community, where it would then take on a life of its own?
These questions remain, and Brennan should now be called to answer them.
