The prosecutors will present about 1,500 pieces of evidence in the next trial over Paul Manafort, the former leader of Donald Trump's election campaign.
According to The Washington Post, the court will consider Manafort's actions when he worked as the political consultant in Ukraine during Viktor Yanukoyvch's rule.
The trial is to begin on September 17, with the jury planning to look into Manafort's activity in 2006-2017.
The outlet also added that three witnesses will be involved in the trial; they already testified in the hearings in Manafort's case.
Earlier, Manafort was found guilty on eight counts of financial crimes, New York Times reported.
After a 16-day trial, Manafort was found guilty of five tax fraud charges, one charge of hiding foreign bank accounts, and two counts of bank fraud. The jury was unable to reach a verdict on the remaining 10 counts, and the judge declared a mistrial on those charges.
Paul Manafort is charged with laundering money and evading taxes over ten years of cooperation with former Ukrainian leaders. Previously, an investigation team released over 300 documents, which reveal the details of Manafort's cooperation with the currently disbanded Party of Regions - the-then pro-presidential and ruling political force in Ukraine. The ex-official faces up to 80 years in prison.
