Manafort was in charge of Trump's campaign when the NY real estate developer accepted the party's presidential nomination at the Republican National Convention in 2016.
Before joining Mr Trump's team in summer 2016, Paul Manafort had worked on a number of Republican presidential campaigns, including those of Gerald Ford in the mid-1970s and Ronald Reagan from 1978 to 1980. They will also argue that Manafort fraudulently obtained millions more through a series of bank loans, including some he obtained while working with the Trump campaign.
His lawyers are seeking to exclude evidence at trial that details Mr Manafort's political lobbying work in Ukraine, saying it would be "irrelevant, prejudicial and unnecessarily time-consuming".
The report goes on to note that prosecutors have asked witnesses to avoid mentioning Trump during their testimony to avoid prejudicing jurors; a decision that was met with approval by United States District Judge T.S. Ellis III.
"What happened here is this involves political consulting work that Manafort and other people, his partner Richard Gates who pleaded guilty in [Robert] Mueller's investigation, this is conduct they were involved in going back to around 2004 and forward to about 2014, and a little bit beyond", McCarthy told Fox News' "America's Newsroom."
It's expected to be rich with tales of lavish spending, secret shell companies and millions of dollars of Ukrainian money flowing through offshore bank accounts and into Manafort's pocket.
Given the strength of the evidence, however, some legal experts have suggested Mr Manafort may be banking on an eventual pardon from Mr Trump, who has called his former campaign chairman a "nice guy" who has been treated unfairly.
Manafort trial to begin; prosecutors have... He is expected to testify against Manafort in the trial.
The trial, scheduled to begin Tuesday with jury selection in Alexandria, Virginia, will give the public its most detailed glimpse of evidence Mueller's team has spent the year accumulating.
Manafort, the former chairman of the Donald Trump presidential campaign, was jailed in mid-June on suspicions of witness tampering.
Mr Manafort has pleaded not guilty to those charges as well. "When Mueller came in, he revived that investigation". At one point, his defence lawyers sued Mueller and the Justice Department, saying they had overstepped their bounds by bringing a prosecution untethered to the core questions of Mueller's investigation - whether Russian Federation worked with the Trump campaign to tip the election.
In Zehnle's retelling it was Gates who was the point person for Manafort's book-keepers and tax preparers.
"It seems to me we're seeing deeper ties that Manafort has had financially with his business deals in the Ukraine and with Russian Federation", said Shanlon Wu, a former lawyer for Manafort associate Rick Gates, who pleaded guilty in February and is aiding Mueller's probe.
