Federal prosecutors are recommending a sentence of seven to nine years in prison for former Trump campaign adviser Roger Stone, according to a court filing Monday.
"Roger Stone obstructed Congress' investigation into Russian interference in the 2016 election, lied under oath and tampered with a witness," the filing read. "And when his crimes were revealed by the indictment in this case, he displayed contempt for this court and the rule of law."
U.S. District Judge Amy Berman Jackson will determine the sentence, which could be the longest delivered from Special Counsel Robert Mueller's investigation. Former Trump campaign chairman Paul Manafort is serving 7 1/2 years for bank fraud, while personal attorney Michael Cohen was sentenced to three years.
The evidence against Stone included that Trump knew about WikiLeaks' plans to release emails damaging to his rival, Hillary Clinton, and Stone lied to Congress to protect the president, according to prosecutors.
Stone's sentence should be consistent with federal sentencing guidelines for his crimes, a range of 87-108 months, Justice Department prosecutors argued, saying the term will "accurately reflect the seriousness of his crimes and promote respect for the law."
Stone is due to face sentencing Feb. 20, after a jury in November found the self-proclaimed "dirty trickster" guilty on seven counts of lying to the U.S. Congress, obstruction and witness tampering.
