PER CURIAM ORDER, filed ORDERED that the motion to supplement the appendix, and the Federal Register notice that petitioner seeks to include in the appendix, be construed as a Federal Rule of Appellate Procedure 28(j) letter advising of supplemental authority, because the Federal Register notice is a judicially noticeable public record document. Therefore, petitioner’s motion to supplement the appendix was unnecessary. It is FURTHER ORDERED that the amended petition for writ of mandamus be denied. Pursuant to D.C. Circuit Rule 36, this disposition will not be published. Before Judges: Millett, Pillard and Wilkins. [19-1120] [Entered: 10/18/2019 10:59 AM]
