It’ll be a big disappointment if it is Halper. He wasn’t part of the Trump campaign. So he’s not a plant. Revelation that it was a plant would be much more damaging to the Deep State.
But Kimberley never says it was a plant; she speculates it was a person who “interact[ed] in some capacity with the Trump campaign.”
Yes, you are right. I think she left open her options. And I am getting around to the sense that it was Halper as well rather than Page. Either Halper or someone in his orbit. If they are really worried about this guy being outted and putting operatives in danger, then they are going to throw up a bunch of red herrings for us to chase. Page, Halper, the Australian diplomat... If they are really worried about him being outted, then it must be because it’s harder to guess his name than it would be to guess the names of one of those guys.
One possibility is that it was the first professor that Papadopoulos met with in March, 2016 who was the informant. All the rest of the smoke might be out there to lead us off the trail. But I have to ask how it was that Papadopoulos ended up talking to that guy anyway. It surely wasn’t a coincidence.
