Gates, who faced a bruising cross-examination, returns to the witness stand Wednesday for additional questioning from a Manafort lawyer who accused the government’s star witness of being immersed in “so many lies” that he can’t even remember them all, and who demanded to know how a jury could possibly trust him.

Lawyers for Manafort, the former Trump campaign chairman, are determined to impugn the credibility of Gates. Defense attorney Kevin Downing began his cross-examination of Gates, Manafort’s longtime deputy and fellow Trump campaign aide, by confronting him on his own lies to special counsel Robert Mueller’s investigators, getting him to admit to an affair and pressing him about hundreds of thousands of dollars he admitted to embezzling from his former boss.

The aggressive questioning was aimed at shifting blame from Manafort onto Gates, who pleaded guilty in Mueller’s investigation and agreed to cooperate with investigators by testifying in the financial fraud trial.

“After all the lies you’ve told and the fraud you’ve committed, you expect this jury to believe you?” Downing asked incredulously.

Gates said he did, but the defense lawyer wasn’t satisfied. He scoffed at the idea that Gates had repented for his actions, noting that prosecutors have said they won’t oppose his bid for probation and getting him to acknowledge he had not repaid the money he had taken from Manafort.

After Gates described his theft as “unauthorized transactions” instead of embezzlement, Downing prodded him to use the latter term — and Gates ultimately relented, saying, “It was embezzlement from Mr. Manafort.”

Prosecutors had braced for the tough questioning by getting Gates to come clean about his own crimes. He told jurors how he disguised millions of dollars in foreign income as loans in order to lower Manafort’s tax bill. Gates recounted how he and Manafort used more than a dozen offshore shell companies and bank accounts in Cyprus to funnel the money, all while concealing the accounts and the income from the IRS.

But the grilling got more intense, and personal, Tuesday afternoon when Downing pressed Gates about a “secret life” he said was funded by embezzlement, including an extramarital affair that Gates himself acknowledged. Gates also said he may have submitted personal expenses for reimbursement by Trump’s inaugural committee, which he helped operate.

After Gates struggled to recall precisely what he had told Mueller’s team, Downing asked if he had been confronted with “so many lies” that he can’t keep his story straight.

Gates implicated himself in broad criminal conduct on the stand, an apparent strategic decision by prosecutors to take some of the steam out of defense questioning. He told jurors he embezzled from Manafort by filing false expense reports. He also said he committed credit card and mortgage fraud, falsified a letter for a colleague involved in an investment deal and made false statements in a deposition at Manafort’s direction.

Prosecutors summoned Gates to give jurors the firsthand account of a co-conspirator they say helped Manafort carry out an elaborate offshore tax-evasion and bank fraud scheme. Gates testified that he and Manafort knew they were committing crimes for years, saying they had stashed money in foreign bank accounts and falsified bank loan documents.

“In Cyprus, they were documented as loans. In reality, it was basically money moving between accounts,” Gates said.

Manafort and Gates were the first two people indicted in Mueller’s investigation into potential ties between Russia and the Trump campaign. Gates pleaded guilty months later and agreed to cooperate in Mueller’s investigation of Manafort, the only American charged by the special counsel to opt for the trial instead of a guilty plea.

The case 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 election effort coordinated with Russia — the central question Mueller’s team has tried to answer. But Trump has shown interest in the proceedings, tweeting support for Manafort.

On Tuesday, Gates did connect one part of the bank fraud charges against Manafort to his role in the Trump campaign.

He said 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 Manafort floated banker Stephen Calk’s name for consideration as Secretary of the Army, a post he ultimately did not get. The email exchange occurred after Manafort left the Trump campaign but while Gates was active on the Trump inauguration committee.

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.

“WTF,” Manafort wrote to Gates in one email shown to the jury. “How could I be blindsided like this. You told me you were on top of this. We need to discuss options. This is a disaster.”

In other testimony, Gates recounted how he converted a PDF of a profit-and-loss statement to a Microsoft Word document so he could doctor it to inflate the business’s income. Gates also fabricated a forgiveness letter for what he said was already a fake loan between Manafort’s consulting company and a Cypriot entity he controlled.

During the testimony, Manafort did not stare Gates down as he did Monday. 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.
