One thing for sure, is there was a spy within the Trump campaign.
Glenn Simpson said they had a human source within the Trump team, who called them (Fusion GPS) sometime in Oct 2016.

And then the tidbit about 2 people in the Trump cabinet who would go along with wearing a wire..
Are there still deep plants on the Trump team?
