The trial of Paul Manafort, left, began in Virginia on Tuesday following an array of financial charges brought by special counsel Robert Mueller, right, who is leading the investigation into Russian meddling in the 2016 us presidential election.
A jury has been seated in the federal trial for Manafort, who served briefly as Trump's campaign manager in 2016.
The charges largely predate the five months Mr Manafort worked on the Trump team in 2016, some of them as campaign chairman.
Outside the courthouse, a handful of protesters displayed a life-sized puppet of Mr Trump and held signs saying "Trump won't do time for you", "It's Mueller time", and "I like your new suit" alongside a photo of Mr Manafort's mug shot.
While prosecutors are not expected to address the question of possible collusion between Trump and Russia, Manafort's case is widely viewed as a test to the legitimacy of Mueller's ongoing probe, which Trump has dismissed as a "witch hunt".
Mr Asonye said Mr Manafort created "bogus" loans, falsified documents and lied to his tax preparer and bookkeeper to hide the money, which he obtained from Ukrainian oligarchs through a series of shell company transfers and later from fraudulently obtained bank loans in the US.
Manafort has pleaded not guilty to all 18 counts.
Prosecutors say he hid millions of dollars in income from lobbying for Ukrainian politicians, failed to pay taxes while spending the money on United States real estate and luxury purchases, and lied to banks in order to take out more than $20 million in loans.
A pretrial hearing on the issue is slated for 9 a.m. (1300 GMT) on Tuesday, before jury selection begins.
The pool of jurors will face questions from both sides and US District Judge T.S. Ellis III as they try to weed out potential prejudice in what has become a highly publicised and politically divisive investigation.
Manafort's defense countered that the true culprit in the case is not Manafort, but Gates. Having his former campaign chairman, who helped run Trump's campaign at a critical point of the election, in the news so consistently shines a negative light on him.
Jury selection is set to begin in the trial of President Donald Trump's former campaign chairman.
The case will likely last two or three weeks in Virginia court.
Manafort has a notorious penchant for expensive things.
But once Mueller's Russian Federation investigation ends, Giuliani told Reuters: "He has a right to consider it". Trump has denied any collusion took place.
Turley said Manafort may be "playing a pardon strategy".
Nine potential jurors indicated they have connections to the Justice Department, including four who said they were current or former federal employees.
On the eve of Tuesday's case, Mr Manafort abandoned his attempt to challenge Mr Mueller in civil court. Prosecutors say Manafort didn't submit the reports from 2011 through 2014, even though he funneled millions through overseas accounts. "He could expose himself to further criminal culpability if he has to expose the full extent of those ties".
Prosecutor Uzo Asonye, a member of Mueller's team, said of Manafort: "A man in this courtroom believed the law did not apply to him". Three Russian companies have also been charged.
