So the mystery appears to be solved.
It’s highly likely that the reason that Epstein KNEW Stef Halper was running anti-Trump operations for both the CIA and British intelligence (see post below) is because his friend Price Andrew (Duke of York) told him.
Andrew was deeply connected with British intelligence. He met Dearlove at the Palace just as Russiagate was kicking off.
Dearlove is the boss of Christopher Steele, with whom Stef Halper closely coordinated.
Professor Christopher Andrew who also attended the meeting with Dearlove at the Palace is another member of the Cambridge Club of the “former” spooks and academics operating out of Cambridge University.
It appears that the Palace officially sanctioned the British intelligence support operation to the Hillary campaign.
Epstein wrote that Obama likely knew that Halper worked for both the Americans and the British (which is illegal) and that both sides payed him.
It appears from numerous documents that Obama asked the Brits to help out Hillary, and Brennan organized for the Cambridge Club to run the op out of the UK.
If the Palace sanctioned it officially, to be carried out by Dearlove, the boss of Christopher Steeele, it would make sense why Steele’s FBI codename was CROWN and the dossier was called “the Crown Material”.
WHOA Eptein emailed his lawyer when CIA/British intelligence operative Stefan Halper was exposed as a spy on the Trump campaign and Administration.
"Halper is the fbi informant. mi5 [British intelligence], CIA. a us citizen working for MI5 calls trump campaign insiders and tries to get info for mi5 and fbi. including after trump takes office. 1. did obama know? if a us citizen working for Britain spies. can they spy on Americans? who pays. paid. wild. Donald focused on this big time.
