U.S. President Donald Trump's longtime friend Roger Stone will urge a federal judge on Tuesday to grant him a new trial, after she sentenced him last week to serve more than three years in prison in a case that angered Trump and rattled the Justice Department.

Stone was convicted of lying to Congress, obstruction and witness tampering in a case that stemmed from former special counsel Robert Mueller's investigation that detailed Russian meddling in the 2016 election to boost Trump's candidacy.

Stone's motion for a new trial is under seal before the U.S. District Court in Washington but it is widely expected to turn on allegations that the jury forewoman in his trial, Tomeka Hart, was politically biased.
