Rick Gates has finished three days' worth of dramatic testimony in federal court against his former business partner, ex-Trump campaign chairman Paul Manafort - but not before defense lawyers caused a stir by pressing him for details on his past infidelity.
Gates, who also worked on Trump's campaign, is the star witness against Manafort.
Day seven of the Paul Manafort trial took a technical turn Wednesday, an indication that prosecutors could be wrapping up their case against the former Trump campaign chairman.
According to Gates, Manafort, who had by then left the campaign, asked Gates in various ways to use his position on Trump's team to do favors for Stephen Calk, a banker who had loaned Manafort millions of dollars - loans that Mueller's team alleges were consummated under false pretenses. "I'm trying to change", Gates said.
In a tense day in court, the campaign strategist's longtime deputy, Rick Gates, told jurors how the pair were paid by Ukrainian oligarchs for their work as political consultants in the country.
Manafort's political work included advising Viktor Yanukovich on policy after he won the Ukrainian presidency, Gates said.
The case against Manafort has little to do with either man's work for the Trump campaign and there's been no discussion during the trial about whether the Trump campaign coordinated with Russian Federation - the central question Mueller's team has tried to answer.
Gates admitted to hiding his own income from the IRS in offshore bank accounts.
Prosecutor Greg Andres addressed the defence lawyer's questions about whether the special counsel's office had tried to coach Gates on how to testify.
Gates said under questioning Wednesday that he told Federal Bureau of Investigation agents and Justice Department lawyers about some of the offshore companies that contained millions of dollars in proceeds from their Ukrainian political work.
Trump was indirectly referenced in multiple ways throughout the testimony, highlighting the risks to the president of Special Counsel Robert Mueller's investigation.
Gates, who is married and has four children, acknowledged having had a "relationship" a decade ago and admitted to stealing from his boss during a "difficult time" in his life by inflating personal expenses. Gates has already pled guilty to two counts in Mueller's probe and testified against Manafort as part of a plea deal with the special counsel's office.
Paul Manafort's former accountant was sacked from a Virginia firm after she told the court she was aware that Manafort's tax returns contained false information. These questions about Gates' extramarital tryst also carried faint echoes of Trump, coming less than a month after the release of a tape in which Trump can be heard discussing buying the rights to the story of a woman who claimed to have had an affair with him. He also is accused of fraudulently obtaining millions more in bank loans, including while he was working on the Trump campaign.
On Tuesday, Gates did connect one part of the bank fraud charges against Manafort to his role in the Trump campaign. He told jurors how he disguised millions of dollars in foreign income as loans in order to lower Manafort's tax bill.
Downing summed up his questioning by asking Gates: "After all these lies, and the fraud you have committed, you expect this jury to believe you?"
After Downing asked Gates Wednesday whether he had multiple affairs, Judge T.S. Ellis had a private conversation, out of earshot of the jury.
Gates described to jurors how he repeatedly submitted fake financial documents at Manafort's behest as his former boss became concerned he was paying too much in taxes and, later, that his funds were drying up.
In one exchange published in court Wednesday, Manafort instructs his Cypriot lawyer, Kypros Chrysostomides - referred to in court as "Dr. K" because, according to Gates, his name is hard to spell and pronounce - to transfer money from the Manafort-controlled Leviathan Ltd.
"Mr. Manafort requested. that we did not disclose foreign bank accounts", Gates testified.
