https://www.cnn.com/2019/02/13/politics/paul-manafort-robert-mueller/index.html The judge ruled that Manafort lied, intentionally, in 3 of the 5 instances cited by Mueller. The most significant of which is about his meeting at the Havana Club (a Kushner owned building) with a Russian Intelligence Officer, Konstantin Kilminik, that happened while Manafort was still Trump's campaign chairman. To be clear, this is a federal judge ruling that Trump's campaign chairman lied to investigators about his coordination with a Russian oligarch. And he lied because, according to Mueller, he believed that telling the full truth would be highly damaging to Donald trump personally. This ruling means that Mueller is no longer contractually obligated to uphold his end of the plea deal (like requesting a reduced sentence for Manafort), but it does not mean that Manafort can withdraw his guilty pleas.
