Stone officially left the Trump campaign on August 8, 2015; however, two associates of Stone have said he collaborated with WikiLeaks founder Julian Assange during the 2016 presidential campaign to discredit Hillary Clinton. Stone and Assange have denied these claims. Nearly three-dozen search warrants were unsealed in April 2020 which revealed a web of contacts between Stone, Assange, and other key 2016 Russian interference figures, and that Stone orchestrated hundreds of fake Facebook accounts and bloggers to run a political influence scheme on social media. On January 25, 2019, Stone was arrested at his Fort Lauderdale, Florida, home in connection with Robert Mueller's Special Counsel investigation and charged in an indictment with witness tampering, obstructing an official proceeding, and five counts of making false statements. Stone was convicted on all seven felony counts in November 2019 and was sentenced to 40 months in prison. On July 10, 2020, days before he was scheduled to report to federal prison, Trump commuted Stone's sentence.
