Manafort is facing multiple charges of money laundering, bank fraud and illegal lobbying.
Paul Manafort could "never see the outside of a jail cell" after a judge revoked his pre-trial house arrest and sent him behind bars on Friday over allegations of witness tampering, former Watergate prosecutor Nick Akerman said.
Last week, Mueller added new charges to his indictment against Manafort for obstruction of justice and conspiracy to obstruct justice, stemming from claims of trying to interfere with potential witnesses.
Earlier Friday, federal prosecutors representing Russian Federation special counsel Robert Mueller and Manafort's attorneys clashed in court, with prosecutors arguing that the former Trump aide deserves to be jailed for "committing a crime while on bail".
They said Manafort didn't know who the government witnesses are and the solution is for prosecutors to say who their witnesses are and the judge can say not to contact those people.
"You've abused the trust placed in you", she said. He also included a comparison to "Comey and Crooked Hillary".
Mr Manafort had already served seven months in home detention in Virginia and was due to face trial in September. He again attempted to distance himself from Manafort.
The charges against Manafort and his business partner Rick Gates, announced October 27 a year ago, were the first indictments by Mueller's investigation.
A federal judge has revoked bail conditions for Trump's ex-campaign chairman, Paul Manafort.
But the witness tampering allegations, which also resulted in new criminal charges, were enough Friday for Manafort to lose his house arrest privileges.
Earlier, Trump lashed out at the entire investigation, labelling it a "ridiculous witch hunt" after a Justice Department watchdog report revealed that several FBI investigators had sent anti-Trump text messages during the 2016 campaign. He will stay in jail until the end of his trials, which are now scheduled for late August and September.
Person D1, Andres said, quickly hung up the phone on Manafort while he was still talking and later contacted the Special Counsel's office.
Mr Manafort has been indicted in both Washington and Virginia on a series of mostly financial-related charges, including conspiring to launder money and defraud the United States.
Mueller has been tasked with investigating Russia's attempts to sway the 2016 presidential election in Trump's favor and whether any Trump associates coordinated with the Kremlin.
President Trump tweeted on Friday to call the decision to jail Manafort "tough".
The obstruction charges flow out of lobbying work in 2012 on behalf of Ukraine's pro-Russian president at the time, Viktor Yanukovych, and his Party of Regions.
