It's not clear yet whether Epstein was ever able to share info with the Russians, but this could explain a lot. From Politico:

"Nearly a month before President Donald Trump met Russian leader Vladimir Putin in Helsinki in 2018, Jeffrey Epstein attempted to pass a message to Russia’s top diplomat: If you want to understand Trump, talk to me."

“I think you might suggest to putin that lavrov can get insight on talking to me,” Epstein wrote in a June 24, 2018, email to Thorbjorn Jagland, a former prime minister of Norway who was leading the Council of Europe at the time of the exchange. Lavrov was an apparent reference to Sergei Lavrov, Russia’s longtime foreign minister."

"In the email exchange, one of hundreds released Wednesday by congressional investigators, Epstein indicated he had previously talked about Trump with Vitaly Churkin, Russia’s forceful ambassador to the United Nations, before Churkin died in 2017."

Jeffrey Epstein claimed he gave Russians insight into Trump

Newly released emails show the late convicted sex offender’s extensive network of foreign contacts, whom he corresponded with about Trump’s policy decisions.

@briankrebs what was he trying to gain? An exit route?
@briankrebs
Now that the #EpsteinFiles are bubbling up, maybe more investigation should be given to the #SteeleDossier. The very document stating what #putiin has over #trump. #USPol

@briankrebs I try not to comment on it much because I recognize I'm not a scholar of Epstein's biography and everything I know is third-hand.

... but it has been suggested that there's something... off about his rags-to-riches story. Holes in the "Where did the money come from" traces that suggest that someone was supporting him under the table for something.

But like I said, I don't actually know.

@[email protected] Don't sleep on Epstein's connection to Bill Barr's dad, Donald, who was the headmaster at Dalton School where he gave the uneducated Epstein his first and most lasting facade of legitimacy.

@briankrebs When it comes to the Epstein story; something "doesn't fit.
