Federal Judge Amy Berman Jackson on Thursday sentenced Roger Stone to 40 months in prison, shrugging off unprecedented meddling by President Trump in a case that involved Trump’s own conduct. A jury in November found Stone guilty of making false statements to Congress, obstruction of justice, and witness tampering. During the 2016 presidential contest, Stone, a longtime political adviser to Trump, established himself as an apparent intermediary between Trump’s campaign and WikiLeaks, according to testimony at Stone’s trial.
