Greg Andres, an attorney with special counsel Robert Mueller's office, said the prosecution is running ahead of schedule.
Trump has recently sought to distance himself from Manafort, tweeting that the former top campaign official "worked for me for a very short time".
U.S. District Judge T.S. Ellis has repeatedly prodded them to move swiftly while seemingly giving the defense more latitude.
Check back for updates on this developing story and read Thursday's Arkansas Democrat-Gazette for full details. Then IRS revenue auditor Michael Welch piled on about the very same facts and figures that formed Manafort's alleged lies on five years of tax returns.
But Weissmann has notably not questioned any witnesses at Manafort's Virginia trial.
And on Wednesday, an Federal Bureau of Investigation forensic accountant said Manafort hid more than 30 offshore accounts in three types of currencies from the IRS.
The testimony bolsters the prosecution's tax-evasion case against Manafort.
Now the trial will likely move into gritty tales of bank fraud. He told jurors how he disguised millions of dollars in foreign income as loans in order to lower Manafort's tax bill.
Morgan Magionos used her own charts along with financial and tax records and emails to buttress the government's detailed accounting of how the former Trump campaign chairman bankrolled an extravagant lifestyle without reporting hidden millions to the government.
Neither were charged in connection with their Trump campaign work. "I thought he was needlessly evasive and argumentative", said Barbara McQuade, a former U.S. Attorney in MI who has been watching the trial and said she observed jurors reacting with negative body language as he testified.
A man prosecutors say has ties to Russian intelligence was also among the beneficial owners of some of the companies. Gates was asked about 11 Cypriot accounts, and he testified that they were all owned by Ukrainian businessmen.

It's now a par 70 that plays 7,329 yards long. "You'll see some hole outs this week by the look of this golf course". I played a practice round with (Mark Calcavecchia), and, you know the tragedies that happened transpired.
Gates struggled so badly to give a straight answer that eventually Judge T S Ellis III was forced to intervene. He finished his testimony Wednesday, Day 7 of the trial.
In one example, Manafort and Gates emailed each other copies of a doctored profit and loss statement they later sent a bank to help Manafort obtain a loan. Gates had testified earlier in the trial about one extra-marital affair.
"Yes, because I'm here to tell the truth and take responsibility for my actions", Gates said.
When asked if he took "unauthorized expenses" from Manafort to "fund your separate secret life", Gates replied, "yes, I acknowledge I had a period of time where I had another relationship".
The jury has heard how Manafort made tens of millions of dollars working for pro-Russian politicians in Ukraine.
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. "I'm not sure why, but there have been certain exchanges at sidebar that have seemed not all that judicious to me", he said.
Still, that testimony has provided jurors with a damning account as Gates testified that he and Manafort knew they were committing crimes for years.
Gates made the statement under cross examination by Manafort attorney Kevin Downing.
Manafort's political work included advising Viktor Yanukovich on policy after he won the Ukrainian presidency, Gates said.
Cindy Laporta testified Friday in the government's case against the former Trump campaign chairman, saying she went along with the scam because she was anxious Manafort and his right-hand-man Rick Gates would sue.
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. He challenged the witness: "Have they [the special counsel's office] confronted you with so many lies you can't remember any of it?" Manafort also included Calk on a list he emailed to Gates of people he wanted to invite to Trump's inauguration.
