Riva Levinson was hired by Manafort in the 1980s, becoming, she says, his "Third World traveler of choice".
On Friday, Manafort was ordered into custody after a federal judge revoked his house arrest, citing newly filed obstruction of justice charges.
According to the Washington Post, Judge Berman Jackson described the decision to send Mr Manafort to prison as "extraordinarily difficult" but said his behaviour - which allegedly included ghost-writing an opinion piece defending his behaviour in an English-speaking newspaper in Ukraine - left her with little choice. "I thought about this long and hard, Mr. Manafort".
"I have no appetite for this", she said.
A June 8 indictment accused Manafort and an aide with tampering with witnesses about their past lobbying for Ukraine's former pro-Russian government.
That's an astounding treasure trove of criminals, and one has to believe Manafort isn't almost done with his investigation. The filing showed that one minute after sending the article, Manafort sent Friedman a message saying he had "made clear" that the group worked only in Europe. He was not placed in handcuffs.
Manafort turned around briefly to wave to his wife in the front row before heading out a door at the back of the courtroom, court witnesses said.
But Giuliani, who worked as a federal prosecutor for close to 10 years and is a former New York City mayor, said he did not see evidence to justify ordering Manafort to jail.
"Didn't know Manafort was the head of the Mob", he said.
He referred to Comey and other senior FBI officials as "the scum at the top" of the bureau and as "total thieves".
In her wind-up to her order, Berman Jackson also gave a brief nod to the bitter environment around the case.

None of the charges against them relate to alleged collusion with Russian Federation. In fact, Manafort served there for almost five months. Kilimnik, who prosecutors say lives in Russian Federation, did not appear in court or respond to an email seeking comment Friday.
A Manafort associate, Konstantin Kilimnik, also was charged with obstruction in connection with the alleged approaches to witnesses.
There's also no guarantee that pardoning Manafort would prevent prosecutors from learning what information he knows. They said he carried out a "sustained campaign of over five weeks" using different phones and apps to try to mold testimony of witnesses.
He faces charges of tax fraud, money laundering, and illegal lobbying.
His trial on the related charges in Virginia is set for July 25.
He had remained on home confinement in Alexandria, Virginia, and had been required to wear an electronic monitoring device.
Manafort, along with a Russian associate, is accused of asking future witnesses in the case to lie to the jury.
Donald Trump's former campaign manager took the helm of his campaign just before the Republican National Convention, a four-day event that was filled with chants of "Lock her up!" aimed at Hillary Clinton. Domin said that at least one witness said Manafort tried to influence or "coach" the story on lobbying methods and practices.
Manafort is now confined to his home in the Washington suburb of Alexandria, Virginia, and forced to wear a Global Positioning System monitoring device. He can leave only for legal meetings, medical needs and religious observances. Jackson issued a warning to Manafort at the time and did not penalize him.
He wears two ankle bracelets that track his movements through Global Positioning System technology, one on each leg.
