A long-time ally of Donald Trump has been found guilty of seven charges, including lying to US politicians, and now faces a potential lengthy jail term.
Roger Stone is the sixth adviser or aide to President Trump to be convicted in connection with the special counsel probe into Russian interference in the 2016 US election.
Prosecutors say his lies related to WikiLeaks and its founder Julian Assange.
On the second day of their deliberations, a jury in Washington DC today found Stone guilty of obstruction, witness tampering and lying to Congress.
Stone had denied any wrongdoing, and claimed the case against him was politically motivated.
He is due to be sentenced on 6th February.
The Washington Post reports the charges could see a legal maximum penalty of 50 years - including 20 for witness tampering - but Stone is likely to face 'far less time' under sentencing guidelines.
Shortly after the verdict, Donald Trump took to Twitter to claim the conviction illustrated a "double standard like never seen before in the history of our country" - listing around a dozen Democrats and other officials he has frequently targeted.
67-year-old Stone has worked as a political lobbyist for decades, and has been involved in high-profile campaigns such as the Nixon campaign in 1972 and the early stages of the Trump campaign.
Although he officially left the Trump presidential campaign in summer 2015, he has remained an outspoken supporter of the US president since Trump's election victory.
Mr Stone had repeatedly faced questions over whether he was in communication with Wikileaks over leaked documents from the Clinton campaign.
