There is, United States v. Manning, Bradley E., PFC, presided over by Colonel Denise Lind. Even in civilian courts trials tend to move slowly, especially when there are many different defence motions filed.
The court-martial was due to start on the 21st of this month, but has been delayed as a result of a motion filed by Manning's defence to dismiss all charges. The hearing for this motion will be on 29 October and the court-martial will now only start after that's resolved, expected to be early next year.
