On October 8, Nachmanoff scheduled a jury trial for January 5, 2026, and issued a pretrial briefing schedule.
The first round of motions is due on October 20, 2025, and the second round is due on October 30. Hearings are set for November 19 and December 9.
Soon after the schedule was set, prosecutors and the defense clashed over the terms and timing of discovery.
The Justice Department filed a motion on October 11 seeking two separate discovery deadlines: one on October 14 for matters related to motions challenging the appointment of the U.S. Attorney and alleging vindictive or selective prosecution, and a second on October 20 for all other materials.

ETA to also note - since smarty pants DOJ brought the case, then all of their ducks should have already been in a row. But we know it wasn't because their whole shtick was fraudulent (which is why previous prosecutors REFUSED to even do this).
