Andrew Weissmann, who spearheaded Robert Mueller’s case against former Trump campaign chairman Paul Manafort, is expected to depart soon in one of the clearest signs yet that Mueller is wrapping up his investigation. Weissmann, one of the team’s top prosecutors, will be at least the third to leave the Department of Justice in recent weeks, along with David Archey and Brandon Van Grack.

News of Weissmann’s departure, which was first reported by NPR Thursday, came after Manafort’s prison sentence was nearly doubled by Judge Amy Berman Jackson on Wednesday, putting the shady consultant behind bars for a total of seven and a half years. Weissmann had been the top prosecutor in that case, which resulted in Manafort’s conviction on eight counts of tax and bank fraud in Virginia last August, and a guilty plea to several other charges in Washington, D.C., a month later. Judge T.S. Ellis sentenced Manafort to a mere 47 months in prison on the first slate of charges, sparking outrage among many who said he had been let off too easy. Jackson, the judge in the D.C. case, added 43 months to the sentence for federal conspiracy charges. “Saying ‘I’m sorry I got caught’ is not an inspiring plea for leniency,” she said as she handed down the sentence.

With the federal case against Manafort concluded, Weissmann will reportedly study and teach at New York University, and work on “a variety of public-service projects,” including one to toughen standards for forensic evidence used in court. As NPR noted, the move suggests there won’t be any more big-time indictments before Mueller’s final report.

Of course, Mueller’s report has been said to be in its final stages any number of times. Ty Cobb, Trump’s former lawyer, famously predicted the investigation would conclude by Thanksgiving of 2017. When that deadline passed, reports forecasted that Mueller would deliver his final report shortly after the November 2018 midterms. And yet, almost a year and a half later, he has yet to release his findings. Most recently, CNN reported that Mueller would hand in his report “as early as next week” . . . more than three weeks ago.

Mueller has been famously tight-lipped about both the substance of his investigation and its timeline, leaving the media, the public, and the targets of the probe to draw their own conclusions. The departure of key members of his team, however, seems to be the most concrete indicator that the investigation’s end is imminent.
