“Papadopoulos had several other interesting encounters during the campaign stretch. TheDCNF reported that in Sept. 2016, he was approached out of the blue by Stefan Halper, a University of Cambridge professor and former U.S. government official.

Halper, who works closely at Cambridge with Sir Richard Dearlove, a former MI6 chief, contacted Papadopoulos about writing a policy paper on Israeli and Cypriot energy issues. Halper, an American, paid Papadopoulos $3,000 for the paper and covered the cost of his room, board, and a flight to London. Papadopoulos met with Halper and one of his assistants for several days in London.
During one of their meetings, Halper asked Papadopoulos about Russia and emails, according to sources close to Papadopouloss version of the encounters.
TheDCNF also learned that Halper approached two other Trump campaign advisers, including Carter Page. Halper invited Page to attend a symposium at Cambridge in July 2016.
Another campaign official told TheDCNF they were contacted by and met with Halper several days before Halpers initial outreach to Papadopoulos. That official, who did not want to be identified, said they were surprised to learn of the Papadopoulos encounter.”
