Conservative writer and conspiracy theorist Jerome Corsi is in plea talks with special counsel Robert Mueller's team, which has been investigating Russian interference in the 2016 presidential election.
Mueller's investigators have reportedly spent months investigating whether Corsi had advance knowledge that WikiLeaks would be publishing emails from the private account of Hillary Clinton's campaign chairman John Podesta, and shared that knowledge with Roger Stone, described as an "associate" of then-candidate Donald Trump.
Corsi confirmed with ABC News on Friday that the plea negotiations are underway.
Last week Corsi claimed that he expects to be indicted by Mueller for perjury, and subsequently bailed on an interview with NBC after his lawyer's call with the special counsel's office.
Mueller's investigators are also looking into whether Stone gave Trump a heads-up of the WikiLeaks dumps, and the focus on Corsi suggests the special counsel is moving closer to determining whether the president's campaign colluded with the Kremlin ahead of the 2016 election.More news: Trump Attacks Admiral McRaven, Who Led Osama bin Laden Raid
"This could be a really dramatic turn in this case, in this investigation", said Deutch. "He looks like he has been squeezed, but as far as I know, he refuses to lie", Stone said.
More than a dozen individuals associated with Stone have been brought in for interviews with the Mueller team and have appeared before a federal grand jury.
Corsi is largely tied to this Russian Federation probe because of his link to Stone. Corsi provided research to Stone during the campaign. Corsi's role in the investigation centers on the possibility that he served as a contact between Stone and Wikileaks.
Corsi injected himself into Stone's situation past year when he claimed that one of his own articles for InfoWars inspired Stone to predict in October 2016 that there would be trouble coming for Hillary Clinton campaign chairman John Podesta.
Stone added that Corsi has been "under a tremendous amount of pressure and it is beginning to affect him profoundly" and that Corsi is "being asked over and over to say things he simply does not believe to have occurred".
