George Papadopoulos is the ‘John Dean’ of the Russia investigation, his fiancee says

He has been mocked by President Trump as a “low level volunteer” and “proven to be a liar.”

But the fiancee of George Papadopoulos, the former Trump campaign adviser who pleaded guilty in October to lying to the FBI about his Russia contacts and is cooperating with special counsel Robert S. Mueller III, says he is being miscast.

“I believe history will remember him like John Dean,”

.. she indicated in an interview that she believes he ultimately will emerge as more than a bit player in the Russia probe — and that his decision to cooperate after he was arrested getting off an airplane at Dulles International Airport in July was a key turning point.

.. Without offering specifics, Mangiante said there is much more that has not yet been told publicly about Papadopoulos’ 10 months as an informal national security adviser to Trump and his interactions with a London-based professor who told Papadopoulos, according to court filings, that the Russians had “dirt” on Democratic candidate Hillary Clinton.

.. Mangiante said she has been extensively interviewed by Mueller’s team, who asked about her own brief stint working for Joseph Mifsud, the same London professor who offered to connect the young Trump aide with the Russians.

.. Mangiante accepted in July 2016 but said she only worked for the group for three months, quickly concluding that it was “a facade for something else.”

She said she never heard Mifsud discuss Russians but quit when she was asked by his partner to attend a secret meeting to discuss Iraq in Tripoli. “I thought it was very suspicious,” she said.
