You're apparently right. Here's exactly what Pryor said:
Many of the complaints against Judge Cannon request that the Chief Circuit Judge remove her from the classified-documents case and reassign the case to a different judge. But neither the Chief Circuit Judge nor the Judicial Council has the authority to take this action under the Rules for Judicial-Conduct and Judicial-Disability Proceedings. See Judicial-Conduct Rule 11 (Chief Judge’s Review); Judicial-Conduct Rule 19 (Judicial-Council Disposition of Petition for Review); Judicial-Conduct Rule 20 (Judicial-Council Action Following Appointment of Special Committee).
However, to be sure, we'd have to see the rules cited. Pryor isn't directly concerned with that: he's annoyed because somebody seems to have started an "orchestrated" campaign to file complaints against Cannon. The Eleventh Circuit has by now received more than a thousand of them, and Pryor doesn't want to see any more. He can hardly be blamed for that. I think these kinds of campaigns are stupid.
But the complaints--presumably at least the unique ones--will be ruled on eventually. So I'm still not entirely certain about what's entailed in that.
