Washington (CNN) Jerome Corsi, a longtime friend and associate of Roger Stone, said Sunday that the information about him in the indictment against Stone is "accurate" and that he will "affirm that if asked to in court."

The indictment , publicly revealed on Friday in connection to special counsel Robert Mueller's investigation, says that during the 2016 presidential election, "Person 1" emailed Stone, a longtime associate of President Donald Trump, to predict that WikiLeaks had more document dumps in the works. It also alleges that Stone directed "Person 1" to get in touch with WikiLeaks founder Julian Assange to get "pending" emails from the organization.

Last week, Corsi confirmed to CNN that he is "Person 1" and that the information about him is "accurate," something he repeated on Sunday to CNN's Jake Tapper on "State of the Union."

"I know my motivation is to tell the truth. And I will affirm that what is in the indictment about me is accurate. And I will affirm that if asked to in court," Corsi told Tapper.
