Lokhova, a Russian born British scholar, calls Halper "the dirty trickster."

She says his past connections to these agencies and the FBI is a 'big tell' as to why he was used to used to gather information on the Trump campaign.

"So you have 17 intelligence agencies in the United States with an $80 billion budget you have thousands if not tens of thousands of trained people working for your intelligence services and, yet, they seek out this complete outsider (Halper) right he's not a trained investigator," she says, describing Halper as an overweight 74 year old.

"He's somebody whose known... has a history of being involved in every single scandal for over forty years," said Lokhova. She says Halper's money trail is the answer.

Lokhova isn't the only one.
