President Trump took another swipe at Robert Mueller on Tuesday, a day after the special counsel accused former Trump campaign manager Paul Manafort of lying to investigators.

“Wait until it comes out how horribly & viciously they are treating people, ruining lives for them refusing to lie,” he wrote on Twitter, adding that Mueller is a “conflicted prosecutor gone rogue.”

The special counsel is “doing TREMENDOUS damage to our Criminal Justice System,” he said.

“Heroes will come of this, and it won’t be Mueller and his terrible Gang of Angry Democrats,” Trump wrote. “The now $30,000,000 Witch Hunt continues and they’ve got nothing but ruined lives.”

Mueller’s investigators said in a court filing Monday that Manafort violated his plea agreement by lying multiple times to FBI and special counsel investigators.

Mueller said Manafort should be sentenced immediately given the alleged breach. He faces a maximum of a decade in jail after pleading guilty in September to several financial crimes and conspiring to obstruct justice. If he is found to have violated the plea agreement, the promised leniency for his sentence in the D.C. case will likely be forfeited. He still faces a separate sentencing from a Virginia case where he was convicted of bank and tax fraud.

He is the highest-profile witness the Mueller team has charged with crimes as they proceed with the Russia investigation, which was opened to uncover any evidence members of the Trump campaign colluded with Russia to sway the 2016 presidential election.

“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 stated.

“He believes he has provided truthful information” and attwmpted to “live up to his cooperation obligations,” Manafort’s lawyers pushed back

Investigators did not go into detail about what they believe Manafort lied about or what led them to that conclusion.
