The Fourth Circuit had intended to resume in person oral arguments at the Lewis F. Powell Jr. Courthouse in Richmond, VA for its September argument calendar.  That return was short-lived, as this morning the Court issued a notice that it was suspending the scheduled in person oral arguments and holding September arguments remotely over Zoom.  That notice, along with the updated schedule of September arguments, can be found here:
