Manafort entered a not guilty plea Thursday in federal court in Alexandria, Virginia, where he faces 18 counts including bank fraud and tax fraud.
The trial was set to begin on July 10.
The former high-powered Washington lobbyist previously pleaded not guilty to five other federal charges, including failing to register as a foreign agent while representing Ukraine's pro-Kremlin government, during a separate arraignment in Washington.
He is accused of laundering millions of dollars he was paid by Viktor F. Yanukovich, a former Ukrainian president with ties to the Kremlin.
It was the second criminal case brought against Manafort by Robert Mueller, the special counsel investigating Russian interference in the 2016 election.
In one instance, Manafort allegedly dealt with an unpaid $300,000 American Express bill by telling a bank that Gates had borrowed his credit card and run up the charges, the indictment says.
Manafort resigned as Trump's campaign chairman in August 2016 after The New York Times reported a Ukrainian government corruption probe found Manafort received almost $13 million off the books from a pro-Russian Ukrainian political party.
Jackson issued the gag order in November, saying that Manafort and others involved in the case had to "refrain from making statements to the media or in public settings" to avoid tainting a jury with pretrial publicity. At the request of prosecutors, charges have been dropped against Gates in Virginia, though they could be resurrected should he fail to live up to his plea agreement.
Ellis also questioned the efficiency of running simultaneous prosecutions in the District and Virginia, though he acknowledged that Manafort could not be forced to waive his right to be tried in the proper venue. Downing suggested Thursday that Manafort would like to face all the charges in Virginia.
Prosecutors told said in court they planned to call 20-25 witnesses and said their arguments could last up to two weeks. He faces up to 15 years on the charges of filing false tax returns and up to 20 years on the charges of failing to report foreign bank accounts.
The judge imposed similar bail conditions on Manafort to those already in place in the District, including home confinement.
Manafort's case is before Judge T.S. Ellis III, a senior judge appointed by President Ronald Reagan in 1987.
