The charges stem from what prosecutors say were Stone's efforts to hide the nature of his discussions during the 2016 election about WikiLeaks, the anti-secrecy group that released thousands of emails stolen from the Democratic National Committee and Clinton campaign chairman John Podesta.
In the indictment, U.S. prosecutors said Mr Stone had "sent and received numerous emails and text messages during the 2016 campaign in which he discussed Organisation 1, its head, and its possession of hacked emails".
Mr Stone appeared at court in shackles later in the morning facing charges of witness tampering, obstruction and lying to Congress.
Mr Stone published a book, The Making of the President 2016, after helping Mr Trump to power.
Born in CT in 1952, Mr Stone first got involved in politics at the age of 8, agitating for Democratic candidate John F Kennedy.
He claims to have left the Trump campaign in 2015 but, as Mueller's probe will likely reveal, Stone reportedly stayed close to the periphery as an "informal adviser". He repeated again that he would not testify against President Trump. Trump liked the "publicity" and the "notoriety" but was not "serious about running", Stone recalled in the interview.
Roger Stone, a longtime political operative who was an official on the Trump campaign, is charged with 7 counts.
Stone has a knack for commanding attention: He sports impeccably tailored suits and close-cropped bleach blond hair and is willing to say just about anything.
"This is not some casual, low-level contributor to the Trump Campaign". It says Stone told campaign officials he had information indicating WikiLeaks had obtained documents damaging to Hillary Clinton's campaign.
Stone was pressed by Stephanopoulos after claiming "I did forget on some occasions" about damning texts and emails procured by investigators given that he'd previously testified about correspondence with associate Randy Credico on the same day. "#CrookedHillary." In October, WikiLeaks released thousands of emails hacked from Podesta's Gmail account. "One is he finds this big Russian conspiracy or collusion with the Russians to influence the election", said Randall Eliason, a George Washington University white-collar criminal law professor and former federal prosecutor.
"I think the way I was treated on Thursday is extraordinary", he said.
Stone's problem, like Michael Flynn's, is not what he did but what he said about what he did.
Though no officials are identified by name, one Trump campaign aide cited in the case is Steve Bannon, who later became Trump's chief White House strategist.
What links Stone to the email hack?
The charges mark the first time the Trump campaign has been publicly tied to WikiLeaks by Mueller's team and add to pressure on the president as the newly installed Democratic majority in the House of Representatives plans to step up investigations of him. "If you buy, you get to supply the guests". If yesterday's indictment is any indication of what's to come, more false statement charges could be coming for other associates.
The indictment referred to an October 2016 email from a "high-ranking Trump Campaign official" asking Stone to inquire about future releases of emails by "Organization 1".
