He said: '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'.
As the campaign shifted into high gear, Stone drew wide scrutiny after WikiLeaks, the anti-secrecy activist group, released thousands of emails hacked from the Democratic National Committee and the campaign of Democratic candidate Hillary Clinton.
Donald Trump says he suffered from one-sided media coverage during the 2016 presidential campaign.
Mueller's prosecutors said Stone lied in testimony to the House Intelligence Committee a year ago and allegedly encouraged another operative to back him up when he testified.
Trump's former informal political advisor, Roger Stone, was indicted on Friday on charges of witness tampering, obstruction of justice, and lying to Congress. He described Robert Mueller as a "runaway Special Prosecutor who is accountable to no one".
The following month, Credico pleaded the 5th Amendment to evade an interview with the House Intelligence Committee. That includes his communications with the Trump campaign, his suggestion that Corsi obtain emails related to the Clinton Foundation from Assange, and his queries to Corsi and Credico about the dirt that WikiLeaks had on Clinton.
CNN aired video of the raid at Mr Stone's Fort Lauderdale, Florida, home, showing agents in body armor using large weapons and night-vision equipment, running up to the home and banging on the door. Stone also said it was "disconcerting that CNN knew I would be arrested before my attorney".
Roger Stone also appeared on Tucker Carlson's show just days prior to his arrest and indictment. Stone is scheduled to appear in court later Friday. 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.
Mr Stone is the sixth Trump aide or adviser charged by Mr Mueller and the 34th person overall. The almost two-year-old probe has exposed multiple contacts between Trump associates and Russian Federation during the campaign and transition period and revealed efforts by several to hide those communications.
The Stone indictment, for instance, reflects an unflattering portrait of a presidential campaign eager to exploit stolen emails about a political opponent.
In the Russian Federation investigation, one Trump aide after another has been accused of lying to investigators, or encouraging others to do so, about Russia-related contacts during the campaign and transition period. The profile featured a picture of his tattoo of Nixon on his back.
"Aras Agalarov, a Russian billionaire who hosted a Miss Universe pageant with Mr. Trump in Moscow, and the billionaire's son, Emin, reached out to Mr. Trump several times".
Trump's critics noted that the arrest showed Mueller's probe getting closer to the president himself.
Two weeks later, Trump began bringing up Clinton's health on the campaign trail.
Through it all, Stone never strayed too far from Trump's orbit.
Within hours of the FBI's arrest, Stone made an initial court appearance Friday morning, where a federal judge set his bond at $250,000 and limited his travel to Florida, New York, Virginia and Washington, D.C.
