Roger Stone

The president has used his clemency power to spare Stone a prison sentence following his conviction in federal court. It's the latest official intercession in a case involving a Trump friend.

Roger Stone, a self-styled "dirty trickster" and longtime adviser to President Trump, is expected to appeal. The president, meanwhile, has left open the door to a possible pardon for Stone.

President Trump's political adviser was found guilty on all counts by a federal jury last year after he was charged with lying to Congress and obstructing its investigation.

William Barr's Justice Department lowered the prison sentence recommendation for Roger Stone, a longtime ally of President Trump, in a move that's led to accusations of political interference.

William Barr told ABC News that he wishes the president wouldn't offer commentary about cases the Justice Department is handling or judges before which its attorneys are arguing.

President Trump had called the seven-to-nine-year sentence prosecutors had initially sought "unfair." His Justice Department then requested a lesser sentence.

Stone faced charges that he lied to congressional investigators and obstructed an official proceeding. He pleaded not guilty and said he had done nothing wrong.
