Defense lawyers for Roger Stone, the longtime political adviser to Donald Trump, called Friday for a new trial, according to a Washington Post report, even as Stone’s sentencing, set for later this month, was at the center of a maelstrom this week in Washington. Stone was convicted late last year of witness tampering and lying to Congress. Four federal prosecutors withdrew from the case this week as higher-ups in the department countermanded their recommendation to U.S. District Judge Amy Berman Jackson that Stone be sentenced to seven to nine years in prison. A tweet from Trump attributed that action directly to Attorney General William Barr. Stone’s lawyers contend that the jury foreman, who came forward this week “to stand up … for the prosecutors,” may not have been sufficiently impartial.Market Pulse Stories are Rapid-fire, short news bursts on stocks and markets as they move.
