PAGE: I had a longstanding relationship with the CIA going back decades, essentially, ... and in this fake Mueller report they just refer to this as, Oh, he's "colluding", if you will, with these Russian intelligence officers.
I'm acting as a source, doing it for our government and, oh, by the way, doing it for free as opposed to these DNC consultants" [who were getting paid by both the DNC and Russian oligarchs, but were also receiving "eleven payments" "as Judicial Watch has revealed"].
That last is a clear reference to Christopher Steele, who received 11 payments from the FBI.
So, Page is essentially saying: I had a longstanding relationship with the CIA [as well as with the FBI], I was providing them with information, gratis, and this is how they pay me back--they accuse me publicly (through leaks) of being a Russian agent.
Who in their right mind would cooperate with US government agencies that treat cooperating witnesses/informants like that? AG Bill Barr speaks of restoring credibility to the DoJ and the Intelligence Community--after revelations like these, that's a long road.
