However, when he was pressed for more details on the charges associated with the plea, and the substance of the negotiations, Corsi declined to comment further.
Jerome Corsi, also an associate of Trump, could help Mueller determine if the Trump campaign had knowledge of the Wikileaks release of hacked Democratic emails during the 2016 presidential campaign, according to the Post.
The right-wing writer and former Infowars editor said on his namesake radio show last week that he expects to be indicted by Mueller for lying to investigators, although he insisted he had committed no wrongdoing.
"Trying to explain yourself to these people is impossible..."
Corsi's attorney declined to comment, as did a spokesman for the special counsel's office. Ted Deutch (D-FL) pointed out on CNN's "The Situation Room" on Friday evening, the information Corsi gives up as part of this agreement could pose consequences for Trump as well.

Just like her wedding sari seen at Lake Como, this gold drape was also reportedly a gift from mother Ujjala Padukone. While the Konkani wedding was held on November 14, the North Indian wedding took place on November 15.
So far, none of the people who have made deals with Mueller have "flipped" on the president, however, and the charges against them have all been for process crimes such as lying to the Federal Bureau of Investigation.
Mueller's team is examining Stone's contacts with WikiLeaks and its founder Julian Assange.
Roger Stone, a longtime political adviser and friend to President Donald Trump, speaks in Boca Raton, Florida, on March 21, 2017. Mueller is investigating allegations by Clinton's camp that Trump "colluded" with Russian Federation to steal the presidential election.
Stone has denied being a conduit for WikiLeaks, which published thousands of emails stolen from Clinton campaign chairman John Podesta in the weeks before the election. "#CrookedHillary." WikiLeaks began releasing Podesta's emails on October 7, 2016.
Mueller's interest in Corsi is believed to stem from his alleged early discussions about efforts to unearth then-candidate Hillary Clinton's emails.
He told AP in a separate statement Friday, "It is clear from his recent videos and his recent interviews that my friend Dr. Corsi has been under a tremendous amount of pressure and it is beginning to affect him profoundly".
