They have tried several times to impugn his credibility before the jury.
Ellis even took aim at journalists, threatening on Monday to kick reporters out of the courtroom if they continue being "disruptive".
Gates added that Manafort also wanted to give the businessman a heads-up about the FBI's interest in the offshore accounts as part of the USA government's efforts to recover assets stolen under former Ukrainian President Viktor Yanukovych. "They may think he's a sleazebag - but that's not going to make them overturn how they view the documents", the former attorney said. Gates said the money he took was sent to his account in the United Kingdom and was never disclosed to his accountants or the USA government.
Mr Manafort and Mr Gates were the first people indicted in Mr Mueller's investigation into potential ties between Russian Federation and the Trump campaign.
Manafort is the first person to be tried on charges brought by Special Counsel Robert Mueller's investigation into Russian interference in the 2016 USA election.
He barked at U.S. Attorney Greg Andres to "focus sharply" - a common refrain of his over the past week - when Andres asked permission for Magionos to testify about charts she put together detailing the flow of money from Manafort's foreign accounts to various vendors in the U.S. But Trump has shown interest in the proceedings, tweeting support for Manafort and suggesting he has been treated worse than gangster Al Capone.
The 46-year-old former political consultant told jurors how Manafort asked for tickets to Trump's inauguration so he could give them to a banker involved in approving a loan at the center of his financial fraud trial.
Gates also said that when their political work in Ukraine dried up in 2015, Manafort had difficulty paying his bills and had no other clients at that time.
Gates, who also worked on Trump's campaign, is the star witness against Manafort.
"It was highly inappropriate to raise the other affairs, and the judge's response was very generous", said Gene Rossi, a former prosecutor who has been attending the trial as a spectator.
Rick Gates leaves federal court in Washington, Feb. 23, 2018.
Earlier Tuesday, Gates told the court that Manafort would frequently pay for clothing, landscaping and other personal expenses using wire transfers directly from his bank accounts in Cyprus and others in St. Vincent and the Grenadines. In a heated moment under cross examination by attorney Kevin Downing, Gates acknowledged that it is "possible" he submitted personal expenses for reimbursement from the committee.
Gates, in turn, has said he engaged in financial maneuverings involving their business activities at Manafort's direction.
He showed jurors how the Federal Bureau of Investigation had painstakingly traced wire transfers from foreign bank accounts to retailers in the U.S. who sold Manafort expensive goods - including the custom men's clothier Alan Couture, where Manafort bought jackets made of ostrich and python skin that each cost five figures. "Mr. Manafort had the same path", Gates said. It's a practice he has admitted to doing to the tune of hundreds of thousands of dollars from Manafort, and under pressure from Downing, he agreed that it could be called embezzlement. When the trial broke for lunch, Manafort looked back at his wife, sitting in the front row, smiled and winked at her, followed by a quick shake of his head, seeming to indicate he was unfazed by the morning's testimony.
Gates finally admitted that he had provided false information prior to striking a plea agreement.
Gates admitted to cheating on his wife about 10 years ago, but denied using company money to fund his affair, even as Downing sarcastically noted the apartment Gates kept in the United Kingdom: "A flat?"
