Jerome Corsi, a conservative writer and associate of President Donald Trump and GOP operative Roger Stone, is reportedly in plea negotiations with Special Counsel Robert Mueller, sources said Friday.

A person with knowledge of the alleged talks told The Washington Post that Corsi has been working with Mueller's team, which is investigating alleged collusion between Trump's presidential campaign and Russian officials, on a possible agreement that could lead him to plead guilty in exchange for leniency.

The newspaper noted that the reported talks could help Mueller determine whether Trump or other campaign advisers had any ties to WikiLeaks' 2016 release of hacked Democratic emails.

Corsi's attorney David Gray and a spokesman for the special counsel declined to comment on the reported negotiations, as did an attorney for Trump, the newspaper reported.

Corsi, who provided research to Stone during the 2016 campaign, said on a recent livestream that he expected prosecutors working for Mueller to indict him on a charge of lying to investigators, according to The Washington Post.

He noted that he had turned over computers, emails and other communications to the special counsel in addition to sitting for several interviews.

Corsi, the newspaper said, added that Mueller's team had said he would be criminally charged.

"I'm going to be indicted. That's what we've been told. Everyone should know that," he reportedly said.

Corsi, meanwhile, told The Daily Caller that prosecutors were focused on whether he had a source with inside information about WikiLeaks' plans to release the emails.

He told the news outlet that in August 2016 he thought, but did not know, that WikiLeaks had the emails -- a theory he reportedly shared with Stone.

Stone has denied speaking with Corsi about the emails.

Mueller has also reportedly been looking to whether Stone has possible ties to WikiLeaks.
