"Accordingly, to prove that Manafort earned that much income, the government must be able to show the extent of the work that he performed for Ukraine."
The exhibits show that Manafort did not just work on multiple Ukrainian elections but did political consulting and lobbying work for Yanukovych outside specific campaigns.
Prosecutors say the evidence is also necessary to illustrate Manafort's relationship with the oligarchs who supported the Party of Regions and who paid him through foreign bank accounts.
Two Democratic consultants who worked with Manafort in Ukraine, Tad Devine and Daniel Rabin, are set to testify against him. Some documents are necessary to show Manafort's connections with those consultants, prosecutors say.
Yanukovych's ouster in 2014 is relevant, the Special Counsel says, "because it explains Manafort's work for a different political party (the Opposition Bloc) and why his income later drops dramatically, which is relevant to the bank frauds that he later committed."
Jury selection is set to begin tomorrow. Manafort faces related charges in Washington, D.C., federal court, where his trial will begin in September.
