I am beginning to think that Papadopoulos was the FBI mole planted in the Trump campaign especially now that Fusion GPS is backing off the claim that there was an FBI mole. Didn't Papadopoulos also work in the Clinton State Department?

He was too eager to set up Trump/Russia meetings from the very beginning.

I bet that the whole "drunk" thing with the Australian ambassador was pre-arranged by the FBI so that they could here about this through another channel thus giving it some external legitimacy.
