President Donald Trump's former campaign manager, Paul Manafort, faces up to 24 years in prison after being found to have violated his plea deal with Special Counsel Robert Mueller's Russia investigation.
Mr Mueller's office said it agreed with a Justice Department calculation filed in a court document that Mr Manafort should be sentenced to between 19 and 24 years and fined between $50,000 and $24m.
Earlier this month, a federal judge agreed with prosecutors that Manafort had "intentionally" lied to investigators about his contacts with a suspected Russian operative, Konstantin Kilimnik, in 2016 and 2017 - despite having pledged to co-operate as part of his September plea agreement.
The judge also ruled that Manafort had lied about a secretive payment he made to a law firm, and lied on another occasion when investigators queried him about a separate, still secret investigation related to the Mueller investigation.
The ruling meant that Mr Mueller no longer has to abide by the deal, in which Manafort agreed to plead guilty to two reduced conspiracy charges, carrying a maximum sentence of 10 years in prison.
Manafort is one of seven former Trump campaign associates who have been charged by the Mueller team.
He was convicted in a court in Virginia last August of eight charges of banking and tax fraud related to his work for Russia-backed political parties in Ukraine between 2004 and 2014.
He was separately charged in Washington with money laundering, witness tampering and other offences, which were consolidated into the two conspiracy charges in the plea bargain.
