April 30 (UPI) -- Political strategist Roger Stone formally filed a notice Thursday to appeal his federal conviction on charges of lying to Congress and witness tampering, related to the House Russia investigation.
Stone, former associate of President Donald Trump's, was convicted last fall on the charges, which also included interfering in the House inquiry. U.S. District Judge Amy Berman Jackson denied Stone a new trial this month after defense attorneys suggested the jury foreman was biased.
