A federal judge in Washington, D.C. has revoked former Trump 2016 campaign chairman Paul Manafort’s bail after prosecutors working for special counsel Robert Mueller presented evidence that he had attempted to tamper with potential witnesses in his money laundering/fraud case, meaning that Manafort will now be sent to jail. He is the first former Trump associate to be imprisoned in relation to Mueller’s investigation; former deputy campaign chairman Rick Gates and former national security adviser Michael Flynn are awaiting sentencing after pleading guilty in the probe.

(Update, 12:10 p.m.: Emerging reports from the courtroom suggest that Judge Amy Berman Jackson got quite salty:

Judge to Paul Manafort: "You have abused the trust placed in you six months ago." On rejected Manafort's lawyer's request for a clearer "no contact" order in lieu of going to jail: "This is not middle school. I can't take his cell phone." https://t.co/UcO5XTnhlM — Zoe Tillman (@ZoeTillman) June 15, 2018

More like Judge Amy Burnman Jackson!)

An indictment filed a week ago alleges that Manafort and a suspected Russian operative named Konstantin Kilimnik obstructed justice by contacting two public relations executives with whom they had worked on an alleged 2012-era scheme to illegally disguise paid lobbying on the behalf of a Russia-backed regime in Ukraine. Prosecutors allege Manafort and Kilimnik contacted the associates and attempted to convey to them that they should disseminate the (allegedly false) narrative that the lobbying in question did not take place in the United States. (The PR executives have not been accused of wrongdoing.)

Asked about the case on Friday morning, Trump said Manafort “has nothing to do with our campaign” and “worked for me for a very short period of time …. for what, 49 days, or something?” Manafort worked for Trump’s campaign from March, 28 2016 until August 19, 2016, which is 145 days.

Manafort is accused of a number of crimes related to his efforts to hide both the unregistered lobbying work he did on behalf of Ukrainian figures beginning in 2006 and the money he received for that work. None of the charges against him bear directly on his work for Trump or the question of whether the Trump campaign abetted Russia’s 2016 attacks on Hillary Clinton, but charges related to those issues could still be filed at a later date.
