Longtime Donald Trump associate Roger Stone says there is “not one shred of evidence” that he was involved with Russian interference in the 2016 election.

Stone is defending himself in a lengthy and combative statement released ahead of a closed-door appearance before the House intelligence committee Tuesday. He has also released a series of supporting documents, including direct messages he exchanged with Guccifer 2.0, the unnamed hacker who has taken credit for breaking into Democratic National Committee email servers.

“While some may label me a dirty trickster, the members of this committee could not point to any tactic that is outside the accepted norms of what political strategists and consultants do today. I do not engage in any illegal activities on behalf of my clients or the causes in which I support,” Stone said in the prepared statement. “There is one ‘trick’ that is not in my bag and that is treason.”

Stone, a Republican strategist who has known Trump for many years and informally advised him during the 2016 campaign, also denies he had advance knowledge of the leak of former Clinton campaign chairman John Podesta’s emails and says he never colluded with WikiLeaks founder Julian Assange. He has long denied that he worked with Russian officials to influence the presidential election.

“I recognize that those who believe that there was collusion between the Trump camp and the Russian state, now say Stone, ‘MUST HAVE’ been involved, but that is not based on one shred of evidence,” Stone writes. “This is nothing more than conjecture, supposition, projection, allegation, and coincidence, none of it proven by evidence or fact.”

Stone’s interview comes as the House and Senate intelligence panels are looking into the Russian meddling and possible links to Trump’s campaign. Stone has been part of the investigation partly because he has said he communicated during the presidential campaign with Guccifer 2.0.

Stone is, for the first time, releasing those communications, which he says are “innocuous.” The direct messages on Twitter, exchanged over a monthlong period, show Stone first congratulating Guccifer for being reinstated on Twitter after he was kicked off, and asking that the account retweet a tweet about how the election could be rigged against Trump. Guccifer writes, “I’m pleased to say that u r great man …. please tell me if I can help u anyhow.”

Stone doesn’t respond again until several weeks later, when Guccifer asks him about an article on a Democratic turnout model. Stone replies “pretty standard.”

On WikiLeaks, Stone said he was kept apprised of Assange’s plans to release emails by a journalist he said served as an “intermediary.” He did not name the journalist.

His statement is heavy on criticism for California Rep. Adam Schiff, the top Democrat on the House intelligence panel, who suggested in March that Stone had a direct line to Russian hackers based on Stone’s tweet “it will soon be the Podesta’s time in the barrel.” Several weeks later, Assange released Podesta’s hacked emails.

Stone says that tweet had nothing to do with the release of emails, but was out of frustration after Podesta’s counterpart on the Trump campaign, former Trump campaign chairman Paul Manafort, resigned.

“Shame on you, Mr. Schiff,” he writes.

Stone has been outspoken in his own defense and asked for his House appearance to be public. But he said the House panel insisted on holding the session behind closed doors.

As his statement was released, Stone held court with about five dozen supporters at the Trump Hotel Monday night, taking photos with the group and offering the Nixon “V” victory sign at one point. He also repeated his criticism of the panel’s top Democrat, saying the committee is “full of Schiff.”

The House panel will also interview former Trump staffer Boris Epshteyn this week, according to a source familiar with the interview. The person declined to be named because the panel’s meetings are private.

Epshteyn, who grew up in Moscow, worked a short time in the White House press office. He left in March and now works as a political analyst for right-leaning Sinclair Broadcasting.

The interviews come as the House and Senate intelligence panels are looking into the meddling and scrutinizing the spread of false news stories and propaganda on social media. The Senate intelligence committee will speak to officials from Twitter Thursday, also behind closed doors.
