Rick Gates, the former top deputy to one-time Trump campaign chairman Paul Manafort, continues to cooperate with investigators in "several ongoing investigations" and so, is not ready for sentencing, according to a Friday court filing.
U.S. District Judge Amy Berman Jackson allowed Gates postponement.
NPR first reported that Weissmann is returning to New York University, where since 2011 he was a senior law school fellow between stints serving as Federal Bureau of Investigation general counsel under then-FBI director Mueller and as chief of the Justice Department's criminal division's fraud section, from which he joined the special counsel probe. If Gates wasn't needed anymore, the parties likely would have asked to set a sentencing date.
It comes amid increasing speculation that Mueller is close to wrapping up the investigation into Russian election meddling and possible collusion with the Trump campaign.
Gates helped the government in obtaining a trial conviction of Manafort past year. That report could be completed even if investigations continue elsewhere, including in the Southern District of NY.
Special Agent in Charge David Archey took on a new job on March 4 as head of the FBI's office in Richmond, Va. It seems quite clear that Gates is being quite helpful and, most likely, assisting Mueller with the investigation into President Trump's inauguration.
Gates pleaded guilty in February 2018 to conspiracy relating to his lobbying work with Manafort in Ukraine. But it's unclear if Friday's delay is an indication that Mueller may submit his confidential report soon or if it's related to the status of the other investigations. CNN has previously reported that federal prosecutors in Manhattan are investigating that inaugural committee and issued a subpoena to the committee earlier this year, asking for documents about its donors, vendors and finances.
