Manafort was chairman of Donald Trump's presidential campaign, and his longtime deputy was part of the campaign, too.
Prosecutor Greg Andres objected to the question before Gates could answer. Manafort's lawyer Kevin Downing asked in the courtroom.
The judge then brought the trial to a standstill late Tuesday afternoon, calling a brief recess.
In general, references to Trump at the trial have been few and far between.
As for the bank fraud charges against Manafort, prosecutors presented the most compelling evidence yet that he knowingly inflated his income when applying for loans.
During the first two days of his testimony, Gates admitted to shielding millions of dollars in over a dozen offshore accounts from United States tax collections - all at Manafort's direction.
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.
Jobs report misses as unemployment rate slides near 18-year low
Faucher writes that as that happens, job growth will slow down because businesses will find it more hard to recruit new hires. The jobs figures follow second quarter data last week showing the United States economy grew at an annualised rate of 4.1%.
Manafort's defense team says it was actually Gates who committed the financial crimes, without Manafort knowing, and Manafort's lawyers also have sought to exploit the guilty plea that Gates has accepted after he was indicted on related charges. They have tried several times to impugn his credibility before the jury.
Manafort, seated at the defence table, stared intently at Gates while his defence attorney hammered him with aggressive questions, but his former business partner carefully avoided his gaze.
After saying Monday that he committed crimes with Manafort, including concealing offshore accounts to avoid reporting them to the US government at tax time and claiming false income to get loans, Manafort defense attorney Kevin Downing asked the witness, "This jury is just supposed to believe you after all the lies that you've told and the fraud you've committed?"
Gates said that he helped fabricate documents to convert some income to a loan to lower Manafort's tax bill.
He is the first subject of special counsel Robert S. Mueller's investigation to stand trial.
Gates pleaded guilty in February to one count of conspiracy against the United States and one count of lying to an Federal Bureau of Investigation agent in exchange for testifying against his former boss. The case has little to do with either man's work for the Trump campaign, which has only tangentially figured in the trial. But Trump has shown interest in the proceedings, tweeting support for Manafort.
For this Manafort was paid US$4million a year, in quarterly payments of US$1million, Gates recalled, though at some point the currency switched from U.S. dollars to Euros.

A contributor's committee nominee, Beathard worked for the Chiefs, Falcons, Dolphins, Redskins and Chargers. Moss closed his speech with a statement to his mother that he considers them both of Hall of Famers.
Those who dealt with Manafort's taxes also testified that even though they asked Manafort whether he maintained any bank accounts overseas, he told them no. Gates also said Manafort floated banker Stephen Calk's name for consideration as Secretary of the Army, a post he ultimately did not get.
Andres followed up: "Did Mr Manafort know?" And the fact that after loaning Manafort millions of dollars Calk became an economic adviser to Trump casts doubt on Trump's famous pledge to "drain the swamp" and puncture the rampant influence peddling in Washington.
Gates, who testified Monday and returned to the witness stand Tuesday, detailed years of alleged lawbreaking at Manafort's political firm and admitted to stealing money from secret overseas bank accounts.
"WTF", Mr Manafort wrote in response, "How could I be blindsided like this".
Gates converted the 2015 DMP P&L to a Word document for Manafort, but there were spacing, font, and other discrepancies between that copy and the original.
Manafort's political work included advising Viktor Yanukovich on policy after he won the Ukrainian presidency, Gates said. He told jurors he embezzled from Manafort by filing false expense reports.
