Manafort was also found guilty of two counts of bank fraud and one count of failing to file foreign bank account reports.
In a note to U.S. District Court Judge T.S. Ellis, the jurors said they had not reached a consensus on the 10 remaining counts in the bank fraud and tax crimes trial. Ellis, in turn, declared a mistrial on those 10 counts.
The Alexandria, Virginia criminal trial was the first borne of charges lodged by special counsel Robert Mueller's investigation into Russian interference in the 2016 campaign. Manafort, 69, faces another federal trial in September in Washington, D.C., which also stems from the Russia probe.
At the end of the 16-day trial, the jury's verdict arrived at nearly the same moment that Trump's longtime personal lawyer, Michael Cohen, pleaded guilty to tax fraud and making an excessive campaign contribution.
