Washington (CNN) Roger Stone associate Jerome Corsi said Friday he is in plea negotiations with special counsel Robert Mueller's office.

Corsi, confirming an earlier Washington Post report , declined to comment further. Last week, he said publicly he expected to be indicted by Mueller for "giving false information to the special counsel or to one of the other grand jury."

Corsi's role in the investigation largely revolves around the possibility that he was an intermediary between Stone -- a longtime Trump ally and confidante -- and WikiLeaks. He has been involved in Mueller's investigation for roughly two months and has participated in multiple interviews with investigators, handed over documents and provided testimony before the grand jury.

Corsi could face any number of charges -- spanning from perjury to making false claims to obstruction of justice. The potential charges could be related to false statements he made about his relationship with WikiLeaks and Stone.

During the 2016 campaign, Stone publicly bragged about having "backchannel communications" with WikiLeaks founder Julian Assange, and on several occasions appeared to predict the WikiLeaks releases that roiled the race in the final stretch of the campaign. But in the two years since President Donald Trump's victory, Stone has walked back those claims and said his "backchannel" was merely New York radio host Randy Credico sharing information about his interviews with Assange. Credico denies serving as an intermediary between the two.
