Stone on Friday denied any wrongdoing, flashing Nixon's famous "victory" sign as he stood outside a Florida courthouse hours after he was arrested by Federal Bureau of Investigation agents who moved on his house before dawn. "What about the fake and unverified 'dossier, ' a total phony con job, that was paid for by Crooked Hillary to damage me and the Trump campaign?"

"There's no circumstance under which I would bear false witness to the president".

Tom Perez, chair of the Democratic National Committee, accused the Trump campaign of being "a willing and active participant in a conspiracy with Russian Federation and Wikileaks" in a statement.

Despite this, he has always said he had no inside information about the contents of the emails in WikiLeaks' possession, or the timing of when they would be released.

But with each new charge, Mueller continues to publicly untangle Trump campaign operations and their intersection with Russia's efforts to hurt Clinton and help Trump.

Stone, with his self-professed political dirty tricks and the tattoo of Richard Nixon on his back, has long lurked in the shadows of Donald Trump's world and was instrumental in guiding him on his first steps to the White House.

Stone told ABC News' George Stephanopoulos Sunday morning he believes he is being wrongly accused of making false statements but if others in then-Republican presidential candidate Donald Trump's 2016 campaign committed illegal acts he would relay that information to Mueller's Russian collusion investigators.

"That's a question I'll have to determine after my attorneys have some discussion if there's wrongdoing by other people in the campaign that I know about, which I know of none", Stone replied.

On Friday, Mr Podesta referenced the cryptic tweet in a post about Mr Stone's indictment, noting it was "Roger's time in the barrel".

Speculation about the specific "senior Trump Campaign official" referred to in the section above has run rampant since Stone's indictment and is unlikely to cease any time soon.

"Stone claims that his communication with "(WikiLeaks) had occurred through a person STONE described as a 'mutual friend, ' 'go-between, ' and 'intermediary.' STONE also continued to communicate with members of the Trump Campaign about Organization 1 and its intended future releases".

He has been charged by special counsel Robert Mueller's investigation into Russian collusion on a number of counts, including lying to Congress and obstructing the investigation.

Once Republicans fill the minority vacancies on the House intelligence committee, the committee will submit all relevant transcripts from other campaign officials and associates who testified to Congress, according to the chairman of that committee, Rep. Adam Schiff (D-Calif.).

The Kremlin has denied interfering in the election. Those indicted include 12 Russian military officers and 13 Russian nationals accused of leading a campaign to interfere in the United States election.

The case comes weeks after Mr Trump's former national security adviser, Michael Flynn, was castigated by a judge in open court and just hours before Paul Manafort, his ex-campaign chairman, appeared on allegations that he had lied to prosecutors.

The 66-year-old favours three-piece suits and reportedly does not wear socks.

Well-known for his political antics and hard-ball tactics, Mr Stone has reveled in being a Washington wheeler-dealer dating back to the Nixon administration. It nearly felt as if Stone knew that Mueller was going after Trump and trying to use him as a means to get to him.

The indictment does not name either the associate or the high-ranking campaign official.
