He was taken to the 500-bed facility hours after prosecutors working for Special Counsel Robert Mueller convinced Judge Amy Berman Jackson that Manafort couldn't be trusted on house arrest any longer.
Prosecutors say the two men tried to get two witnesses to say that lobbying work on behalf of Ukraine and carried out by clandestinely paid former politicians occurred only in Europe and not the USA, a contention the witnesses said they knew was false.
Manafort, President Trump's ex-campaign chairman, had been allowed to post a $10 million bond and remain at home while awaiting his trial on a host of charges, including money laundering and false statements. His trial on related charges in Virginia is set for July.
But the president also stuck up for him, suggesting that Manafort's alleged crimes are too old to prosecute. "In the end, I can't turn a blind eye to these allegations", the judge said.
Kilimnik, whom USA authorities suspect of having ties to Russian intelligence, served as Manafort's point man in Ukraine.
The distinction matters because unregistered foreign lobbying in the U.S.is a crime, while lobbying exclusively in Europe would be outside the special counsel's jurisdiction.
Manafort's attorneys have accused prosecutors of conjuring a "sinister plot" out of "innocuous" contacts.
Jackson said she was "very troubled" by Manafort's contacts with witnesses.
In addition to the texts and phone calls cited in the government's earlier filing, Andres said one of the witnesses had provided an affidavit through his lawyer about one call from Manafort that was completed.
"There is nothing on the record of this court that assures that Mr. Manafort will abide by (any ) conditions" of pre-trial release short of jail, Andres said.
Manafort and his Russian business partner allegedly asked European contacts to testify that their lobbying work did not take place in the United States, CBS News' Kenneth Craig reports. One document was a 2013 memo from Manafort to former Ukrainian President Viktor Yanukovych. She also refused to lay out which witnesses were off-limits.
'This is not middle school.
Manafort has denied any wrongdoing and pleaded not guilty.
Manafort is awaiting trial scheduled to start later this year after having been charged in October with bank fraud, conspiracy to launder money, and other crimes. Prosecutors say Manafort directed the group's work and secretly funneled more than $2 million to it to take positions favourable to Ukraine including by lobbying in the USA without disclosing that they were being paid to favourably represent the country.
Legal experts say Mueller wants to keep applying pressure on Manafort to plead guilty and assist prosecutors as Gates did and is cooperating with the probe after cutting a plea deal.
