Two sources familiar with the inquiry tell McClatchy that investigators are working to confirm information indicating that Manafort and the consulting firms he led earned between $80 million and $100 million over a decade from pro-Moscow Ukrainian and Russian clients.
Mueller’s expanded focus on Manafort’s complicated financial picture is zeroing in on whether he may have evaded taxes or engaged in any money laundering schemes, the sources say, and the hunt for his financial records through a labyrinth of offshore bank and business accounts has become an important prong of the investigation.
Overall, the probe centers on whether anyone on Donald Trump’s campaign, or other Trump associates, assisted Moscow’s election meddling. Russia’s cyber mischief last year was designed to help the real estate mogul win in November.
As it was reported earlier Manafort is considered one of key figures in case of Trump's link with Russia. American investigators hope to encourage him to cooperate with regard to investigating a possible collusion between the Trump campaign members and Russia.
