Between 19 and 24 years... that's how long prosecutors for Special Counsel Robert Mueller say Paul Manafort should spend in prison.

Mueller's team says that President Donald Trump's former campaign manager should also be fined somewhere between $50,000 and $24 million.

In a sentencing memo filed on Friday, the prosecutors wrote that Manafort "cheated the U.S. Treasury and the public out of more than $6 million in taxes at a time when he had substantial resources." Manafort was convicted last year on eight counts of bank and tax fraud.

The sentencing memo came just days after a federal judge ruled that Manafort had lied to investigators in a parallel case, despite a pledge to cooperate.

Manafort was one of the first people in Trump's orbit to face criminal charges, as part of Mueller's probe into whether Trump's campaign colluded with Russia to win the 2016 election.

Another person in Trump's circle with legal troubles: longtime adviser Roger Stone.

He was indicted last month for lying to Congress about his communications with WikiLeaks about the release of hacked Democratic Party emails.

A judge on Friday issued a gag order for Stone's case, barring prosecutors and defendents from speaking wth the media when they are near the court house.

Trump has denied colluding and called the probe a witch hunt.
