Carter Page was/is an FBI INFORMANT that was put in the campaign to SPY!! That’s the reason NO charges were ever considered for him!
Carter Page was an Annapolis grad and a Naval officer. He spoke fluent Russian. I can’t help noticing that he has the resume of a CIA Moscow station chief. And by shear coincidence (I’m sure) he was stationed in Moscow for several years.
Then he comes back to the US and is immediately sucked into an FBI counterintelligence investigation. No sooner does he beat the rap on that and then he’s immediately sucked into another counterintelligence investigation that is unrelated to the first one. What an unlucky guy.
