Defence lawyers acting for US President Donald Trump's former campaign chairman, Paul Manafort, have rested their case, without calling witnesses on his behalf.
He told the judge he did not want to testify in his own defence against bank and tax fraud charges.
A jury could begin deliberating on the case later today, according to US media.
During ten days of testimony, some 20 prosecution witnesses described how Mr Manafort allegedly avoided paying tax on at least $16m of income and repeatedly lied to banks as he borrowed millions more.
The 69-year-old faces 18 counts related to tax and bank fraud.
The two-week trial heard details of Mr Manafort's lavish spending on clothing, including $15,000 for an ostrich-skin bomber jacket and landscaping one of his homes with a flower bed shaped like the letter "M".
The jury heard from a former partner and a former accountant on how the long-time political consultant doctored his accounts and laundered tens of millions of dollars through offshore banks.
The case was the first to be tried in the investigation by Special Counsel Robert Mueller, which is focused on possible illegal collusion between Mr Trump's 2016 election campaign and Russia.
Mr Trump has denounced the probe as a politically motivated "witch-hunt" and denied there was any collusion with Russia to defeat Democratic presidential nominee Hillary Clinton.
While several others charged in the investigation, including Mr Manafort's former aide Richard Gates, have pleaded guilty and agreed to cooperate in the Mueller probe, Mr Manafort has stubbornly battled the prosecution's charges.
The charges against Mr Manafort relate mostly to his handling of money he earned working for pro-Russian politicians in Ukraine from 2005 to 2014, including helping tycoon Viktor Yanukovych become president in 2010.
Besides the trial under way in the US district court in Alexandria, Virginia, Mr Manafort faces multiple charges of conspiracy, money laundering and obstruction of justice filed separately by Mr Mueller's team in the Washington DC district court.
