Washington - President Donald Trump's former campaign chair, Paul Manafort, and Manafort's business associate Rick Gates face decades in federal prison and millions of dollars in potential fines if convicted on all counts in a sprawling federal indictment unsealed Monday.Manafort potentially faces up to 80 years in prison, according to a review of the federal charges and the relevant statutes by The Associated Press. Gates, who also worked for the Trump campaign, faces up to 70 years.Special counsel Robert Mueller could still file additional charges against the pair.If convicted at trial, the law gives federal judges wide latitude in imposing prison sentences and fines. White-collar defendants often end up serving only a fraction of their statutory maximum sentences, especially if they reach a pre-trial agreement with prosecutors as part of an admission of guilt.Prosecutors allege that Manafort and Gates worked as unregistered agents of the government of Ukraine and the Party of Regions, a pro-Russian political party led by Victor Yanukovych. While serving as president of the former Soviet republic from 2010 to 2014, Yanukovych was closely aligned with Russian President Vladimir Putin.The indictment says that up to $75m flowed through overseas accounts controlled by the two Americans. Manafort is alleged to have laundered more than $18m he used to buy property and goods in the United States. Gates is alleged to have transferred more than $3m to accounts he controlled.Manafort was released on Monday on home confinement after posting a $10m bond. Gates was released on a $5m bond.George PapadopoulosIn a separate development on Monday, newly unsealed court documents show George Papadopoulos, a former foreign policy adviser to Trump, pleaded guilty on October 5.s part of a sworn statement to the court, Papadopoulos says he repeatedly met in 2016 with Russians offering "dirt" on Democratic presidential candidate Hillary Clinton. Papadopoulos says he then relayed that and other messages from the Russians to senior members of Trump's GOP campaign.Papadopoulos' guilty plea came as part of an agreement with prosecutors that signals he could avoid prison time as part of an apparent deal to cooperate with Mueller's team.A summary of the charges encompassed in the 31-page indictment of Manafort and Gates, and the potential penalties:__COUNT ONE: Conspiracy Against the United StatesBoth men are charged with conspiring together and with others to knowingly and intentionally defraud and commit crimes against the United States between 2006 and 2017.
