Who was Manafort accused of contacting?
Kilimnik worked with Manafort in Ukraine during that time, and during the 2016 election they were reportedly in regular contact.
Prosecutors have said that Manafort's role in the campaign and long-standing ties to Russian-backed politicians, financiers and others merited investigation into whether any of them served as back channels to Russia.
While under house arrest, Manafort allegedly tried to use his former Russian fixer, Konstantin Kilimnik, to contact two witnesses in his money laundering case and persuade them not to make certain statements to investigators.
Judge Jackson said there wasn't another option than to revoke bail.
Trump got asked about Manafort this morning on the White House North Lawn, after he staged his spontaneous visit to Fox & Friends station on the lawn.
Mueller's team this month asked the judge to revoke Manafort's bail, saying his "obstructive" conduct "instils little confidence that restrictions short of detention will assure Manafort's compliance with the court's orders and prevent him from committing further crimes". "I can't take his cellphone". He's first scheduled to go to trial in Virginia on another case brought by Mueller involving charges of bank fraud, tax evasion and failing to report foreign bank accounts.
"You will see if you do any fact-checking that I was the person that negotiated the framework which is based upon which Ukraine is now a part of Europe".
The charges against Manafort and his business partner Rick Gates, announced October 27 a year ago, were the first indictments by Mueller's investigation. "And some people say, "he lied" and some people say, 'he didn't lie.' Really it turned out maybe he didn't lie", he told reporters.
Manafort has pleaded not guilty and said he's done nothing wrong.
The response added that it was not a crime for Mr Manafort "to communicate his view to others, especially when he is not aware of who the Special Counsel may call as witnesses". The charges against Manafort in Washington include failing to register as a foreign agent for the pro-Russia Ukrainian government under former President Viktor Yanukovych. Kilimnik is believed to be in Moscow - and therefore safe from arrest because Russian Federation does not extradite its citizens.
The witnesses worked with Manafort in organizing a group of former European officials who lobbied within the US without registering as required by law. Mueller's office has described Kilimnik as a Russian intelligence asset who was active through the 2016 election.
