Donald Trump confidant Roger Stone 'weaponized information stolen by Russia' to get the President elected in 2016 and should be prosecuted for treason, the former head of the Democratic National Committee has claimed.

Congresswoman Debbie Wasserman Schultz accused Stone of breaking the law in his alleged attempts to use the illegally obtained DNC emails in Trump's favour during the 2016 election campaign.

Ms Wasserman Schultz, who resigned as DNC chair in response to the leak, said Stone 'needed to be prosecuted' and claimed he had worked with high-level Trump campaign officials to attempt to exploit the hacked emails.

'In this case with Roger Stone, he literally weaponized information stolen by (Russian President) Vladimir Putin to help elect Donald Trump president,' she told CNN.

'He worked with high-level campaign officials from the Trump campaign who were directed by someone even higher essentially to make sure that they could traffic in information stolen by a foreign enemy state to elect the candidate that he supported president of the United States, and it was a disgusting and traitorous act, and it needs to be prosecuted.'

The leaked DNC emails sowed division among Democratic voters by appearing to show party officials favored Clinton over the insurgent candidacy of Senator Bernie Sanders.

While Stone's indictment charges him with seven felonies, including witness tampering, obstruction and false statements, it does not state whether his or the Trump's campaign's interest in exploiting Russia-hacked emails about Democrat Hillary Clinton crossed a legal line.

It alleges that Stone informed unidentified senior Trump campaign officials of what Stone was hearing about plans by the anti-secrecy website WikiLeaks regarding the hacked emails.

It says a senior Trump campaign official 'was directed' to contact Stone about additional releases and 'what other damaging information' WikiLeaks had 'regarding the Clinton campaign.'

Though those allegations don't form the basis of any of the charges against Stone, their inclusion in the 24-page indictment could signal that special counsel Robert Mueller isn't done with that prong of the investigation.

All told, Mueller has charged six Trump associates and 34 people overall, along with three companies. It is unclear when the investigation might end.

'As I have said previously, there is no circumstance whatsoever under which I will bear false witness against the president, nor will I make up lies to ease the pressure on myself,' Stone said.

He denied prosecutors' accusation that he repeatedly lied to the House Intelligence Committee, including when he said he had not discussed his pursuit of the stolen emails with any Trump campaign officials. Stone has previously denied that he ever bullied other witnesses to change their testimony, which is another allegation he faces.

Stone's ties to Trump go back four decades. Stone has urged Trump to run for president since 1988, was chairman of his 2000 presidential exploratory committee and was a consultant when Trump considered running in 2012.

Stone briefly worked for the 2016 Trump campaign but left in August 2015. The campaign said it fired him after he tried to grab too much of the spotlight. Stone insisted that he quit.

Thereafter, he still played a key promotional role for Trump and communicated with people in his camp.
