FBI accountant Morgan Magionos said this during the trial of Manafort on bank and tax fraud charges, according to The Washington Post.
"Manafort took in $60 million over five years, including $31 million from Ukrainian politicians in 2012," the report said.
According to Magionos, more than $60 million flowed through Manafort's overseas accounts between 2010 and 2014, and he spent $15 million of that on homes, clothes and other personal purchases.
She said that in 2012, Manafort spent the most money - more than $9.2 million, mostly on real estate.
Prosecutors say Manafort paid taxes on only about half of his foreign income. He is also accused in Washington, D.C., federal court of failing to register as a foreign agent for his work in Ukraine. He did register in June 2017, but Magionos testified that in those filings, he understated his foreign income significantly.
Earlier, Manafort's former business partner Rick Gates said in court that Manafort had been receiving millions from Ukraine through fake firms controlled by Ukrainian politicians and oligarchs. According to Gates, these companies were controlled by people from Yanukovych's entourage. Former Transport Minister Borys Kolesnikov and Head of the Presidential Administration Serhiy Liovochkin were named in this regard. In addition, Ukrainian oligarch Victor Pinchuk, who donated $150,000 to the Donald J. Trump Foundation, is also on the list.
