Special counsel Robert Mueller is eyeing new charges for President Trump’s former campaign manager Paul Manafort after his plea deal fell apart over allegations of lying to investigators, prosecutors said Friday.

During a hearing in a Washington, DC, courtroom, federal Judge Amy Berman Jackson said Manafort would tentatively be sentenced March 5.

Jackson also ordered Mueller’s team to submit a report to the court Dec. 7 outlining how Manafort had breached his plea deal with federal prosecutors.

Mueller’s team said Manafort had repeatedly lied to them after agreeing to cooperate in their investigation of Russian election meddling and possible collusion with Trump’s campaign.

Jackson said she would hold a hearing in January to decide whether Manafort had breached his agreement, but gave no specific date.

Manafort, a longtime Washington consultant with deep ties to shady pro-Kremlin oligarchs, joined Trump’s campaign in March 2016 and rose to chairman before resigning five months later.

He faces up to five years in prison on each charge in his plea agreement.

He also is set to be sentenced on eight felony counts in a separate case in Virginia in February.

Mueller told the court Monday that Manafort had since lied to investigators, nullifying their deal and clearing the way for sentencing.

Manafort, in the same filing, disagreed with the special counsel but also asked the court to hand down his sentence.

The ruling Monday was the start of a tumultuous week for the commander-in-chief, which included Thursday’s guilty plea by his longtime lawyer and fixer Michael Cohen.

Cohen told prosecutors he had lied when he said an effort to score a deal to build a Trump Tower in Moscow fizzled in January 2016.

The talks continued until that June, as the campaign season was heating up, and Trump was kept abreast of the progress on a regular basis.

Those and other developments — including allegations that Trump crony Roger Stone was in contact with WikiLeaks founder Julian Assange months before hacked emails from Hillary Clinton’s campaign were leaked — have enraged the president, according to multiple reports.

Trump has fired back on Twitter, with a steady flow of posts attacking what he calls Mueller’s “Witch Hunt” even as he was meeting with world leaders at the G20 summit in Argentina.

Trump has called Cohen “weak,” “not very smart” and “a liar,” charging that he made up the Trump Tower story to get a lighter sentence.

But Rudy Giuliani, Trump’s lawyer, said Cohen’s version of events matches what Trump gave Mueller in his written responses to some of the special prosecutor’s questions.

Trump has repeatedly denied that he or his campaign colluded with Russia.
