Ex-Trump campaign chief Paul Manafort broke plea deal, lied to prosecutors, Mueller says
  • Special counsel Robert Mueller alleged Monday that former Trump campaign chief Paul Manafort lied to investigators, violating his plea agreement, according to a court filing.

  • Manafort, meanwhile, "believes he has provided truthful information and does not agree with the government's characterization or that he has breached the agreement," according to the filing.

  • The special counsel and Manafort both asked the judge to sentence the former Trump campaign chairman.

Special counsel Robert Mueller alleged Monday that former Trump campaign chief Paul Manafort lied to investigators, violating his plea agreement, according to a court filing.

"After signing the plea agreement, Manafort committed federal crimes by lying to the Federal Bureau of Investigation and the Special Counsel's Office on a variety of subject matters, which constitute breaches of the agreement," prosecutors said in the document, filed in U.S. District Court in Washington, D.C.

Manafort, meanwhile, "believes he has provided truthful information and does not agree with the government's characterization or that he has breached the agreement," according to the filing.

The filing notes that Manafort's alleged breach maintains all of his obligations under the deal, but relieves the special counsel of its own duties – "including its agreement to a reduction in the Sentencing Guidelines for acceptance of responsibility."

The special counsel and Manafort both asked the judge to sentence the former Trump campaign chairman.

The filing did not mention what Manafort is specifically alleged to have lied about. It was also not clear whether Mueller will file new charges against Manafort in light of the allegations.

A spokesman for the special counsel declined to comment beyond what is in Monday's filing.

This is not the first time Manafort has been called out by the special counsel for breaching the terms of his deals with them. In June, Manafort was sent to jail pending his then-upcoming trials after investigators accused him of witness tampering. The decision in the U.S. attorneys' favor from U.S. District Court Judge Amy Berman Jackson revoked Manafort's $10 million bond.

Mueller is investigating Russia's attack on the 2016 election as well as potential ties between the Kremlin and President Donald Trump 's campaign. Trump has repeatedly denied that his campaign colluded with the Russians to undermine the campaign of Democrat Hillary Clinton.

Manafort had faced prosecution by Mueller in two separate cases, one in Washington, D.C., the other in Virginia. In September, Manafort cut a deal with Mueller's team and agreed to plead guilty to charges related that he was engaged in a conspiracy involving money laundering, tax fraud, failing to report foreign bank accounts, violating rules requiring registration of foreign agents, lying and witness tampering. The deal came a few weeks after a jury in Virginia found him guilty on several counts of financial fraud .
