Jerome Corsi, whose role in Mueller's investigation into Russian meddling in the 2016 election largely revolves around the possibility that he was an intermediary between Stone and WikiLeaks, said he was offered a deal to plea on one count of perjury.
"They can put me in prison the rest of my life. I am not going to sign a lie," Corsi told CNN in a phone call.
Asked what happens now that he is refusing, Corsi responded: "I don't know."

A spokesman for the special counsel's office had no comment.

Last week, Corsi acknowledged he was in plea negotiations with Mueller's office, and earlier this month, he said he expected to be indicted for "giving false information to the special counsel or to one of the other grand jury."

Corsi said Monday that he believed he would by lying by signing the plea agreement because he says he did not willfully mislead anyone. 

Describing his experience with Mueller's team as "like being interrogated as a POW in the Korean War," Corsi said after two months of questioning, prosecutors believed they caught him in various lies and did not appear to believe him when he said he could not recall certain events. 

Corsi insisted he had no contact with WikiLeaks founder Julian Assange and that "investigators were so mad because I didn't give them what they wanted."
