(CNN) New court documents in Paul Manafort's criminal case give the fullest picture yet of what prosecutors say was the former Trump campaign chairman's financial reliance on Ukrainians suspected of corruption and a Russian oligarch, while he allegedly schemed to defraud banks and the US government.

A Virginia federal court unveiled several new details on Tuesday in two search warrants and accompanying affidavits used to search Paul Manafort's properties.

The search warrant documents, which have been available in court records for months but previously had dozens of pages redacted, reveal for the first time how prosecutors believe former Ukrainian President Viktor Yanukovych, the Ukrainian's financial backer Rinat Akhmetov and Russian oligarch Oleg Deripaska propped up Manafort's alleged crimes.

One search warrant allowed federal investigators to remove files from a storage unit in Alexandria last May, while the other let them sweep his Alexandria residence in July 2017.
