The jury returned its verdict on day two of deliberations in Washington DC. The case against Stone was the last remaining case brought forth by former special counsel Robert Mueller's investigation.
The charges also included witness tampering and obstruction the House investigation into whether Trump's campaign colluded with Russian Federation to affect the 2016 election.
Randy Credico, whom Stone falsely claimed was his intermediary to Wikileaks in the summer of 2016, was another major witness for prosecutors.
Prosecutors asked the judge to take Stone into custody immediately.
Based on his charges, Stone could serve decades in prison. He did not testify during the trial and his lawyers did not call any witnesses in his defence.
Stone wanted to contact Jared Kushner in order to "debrief" the president's son-in-law about hacked emails that were damaging to Hillary Clinton during the 2016 presidential campaign, a former Trump campaign aide said Tuesday.
Roger Stone, a longtime friend and ally of President Donald Trump, has been found guilty at his trial in federal court in Washington.
The trial featured multiple references to the film "The Godfather Part II", a Bernie Sanders impression by a prosecution witness, and testimony by political heavyweights including former Trump campaign CEO Steve Bannon and former Trump deputy campaign chairman Rick Gates. Indeed, much of the case centered on Trump and Stone's interactions between WikiLeaks and the Trump campaign.
Lying to the House about Wikileaks-related communications with the Trump campaign was one of the counts Stone was convicted of Friday.
Declaring WikiLeaks "is an arm of the Russian government" - yes, someone actually said that - she misread Stone's guilty verdict as proof he had been "talking to the WikiLeaks people". Those counts include lying to Congress and witness tampering.
During the trial, prosecutors revealed several phone calls placed between Trump and Stone, including a July 2016 conversation in which Gates testified that Trump and Stone spoke about the planned release of hacked Democratic emails. Nevertheless, prosecutors blamed Stone for lawmakers' failure to "pursue promising leads" and said it was Stone's falsehoods that caused them to come to the wrong conclusion in their final Russiagate report. "I'm going to take that dog away from you", he said in the email, which Credico read aloud in court.
