As for Stone, he said Friday's indictment of 12 Russian military officers accused of interfering in the 2016 presidential election shows "no evidence of collaboration or collusion" on his part.
When the Justice Department released an indictment naming 12 Russians connected to a massive 2016 United States presidential election hack attack, Friday, it noted that a senior member of the Trump campaign actively communicated with the hackers.
However, details of a conversation between Guccifer 2.0 and the unnamed person mirrors messages released publicly by Stone, a conservative political operative with ties to Donald Trump dating back decades.
Earlier Friday, Stone acknowledged to CNN that an exchange in the indictment matches messages he previously released, but initially maintained that he did not believe that he is the unnamed person in the indictment.
"First of all, I think this should change the mind of any Republican voter that doesn't want to Donald Trump to be impeached", Nunberg said.
"Schiff: Mr. Stone was in direct communication with a creature of Russian GRU, Guccifer 2.0", Stone told The Washington Post for a report in April 2017 while reciting testimony by U.S. Representative Adam Schiff of California. Stone claims that his communication with "Guccifer 2.0" was "so perfunctory, brief and banal I had forgotten it".
Stone, speaking to CNN's Chris Cuomo, said "I certainly had a 24 word exchange with the persona Guccifer 2.0 over Twitter direct messages". "This exchange is entirely public and provides no evidence of collaboration or collusion with Guccifer 2.0 or anyone else in the alleged hacking of the DNC emails". "If you were going to engage in espionage, I don't think that's where you would do it".
Trump told the Washington Post he chose to terminate Stone, "because he no longer serves a useful function for my campaign".
He said, in a statement he shared with the Herald yesterday, that his exchange with Guccifer 2.0 - an alleged social media front for the hacking Russians - was a "benign" after-the-fact exchange.
The dates and content of the messages described in the indictment between the US person in regular contact with senior members of Trump's presidential campaign and Guccifer 2.0 match verbatim two screenshots Stone published on his website in March of 2017 of the direct message exchange he had with Guccifer 2.0 on Twitter in 2016.
Referring to remarks from Deputy Attorney General Rod Rosenstein on Friday, Stone said, "Look, Rosenstein said in his comments that they knew of no crime by U.S. citizens. I was not in regular contact with campaign officials", he said in the CNN interview.
"When I communicated with Roger about this, Roger told me he had met with Assange and I believed him at the time".
WikiLeaks first published on October 7, 2016, a cache of Podesta's hacked emails, some of which described internal conflicts within the Clinton Foundation. There is no allegation in this indictment that any American citizen committed a crime.
Stone declined to comment further on the matter yesterday.
The indictment of Russian nationals further expands on the USA intelligence community's assessment a year ago that Russia meddled in the 2016 election in an effort to assist Trump's candidacy.
Friday's indictment comes three days before President Donald Trump is scheduled to meet with Russian President Vladimir Putin in Helsinki, Finland, a something that Nunberg called into question.
