The United States has filed its reply brief, which you can find here.
No other amicus briefs have yet been docketed on PACER, but they could well appear later this evening or tomorrow morning. (It appears that at least one brief -- to be filed by former U.S. Attorneys General William Barr, Edwin Meese, III, and Dick Thornburg -- will be filed on Friday, with the permission of the District Court.)
