You may recall that when the President issued an Executive Order changing the hiring process for Administrative Law Judges (ALJs) to allow agencies to hire with few formalities or limitations I raised the question of whether Trump's order complied with the Administrative Procedure Act (APA) which normally requires that proposed changes to regulations be published in the Federal Register for public comment before they can come into effect. I didn't pursue this issue since I assumed there had to be some obscure provision in the civil service laws that allowed the President to do this. Valerie C. Brannon of the Congressional Research Service (which is part of the Congress) pursued this issue and found that there are serious APA problems with the Trump Executive Order. I doubt that agencies will even try to hire ALJs under the new process.
This Executive Order is an exemplar of the Trump Administration -- trying to heroically and simplistically solve difficult problems with the stroke of a pen while dissembling about the reasons for the actions that are taken (claiming the Order was a response to a Supreme Court decision when it wasn't), all coupled with incompetent execution. If Trump and those who work for him weren't such bumbling fools, he'd be a lot more dangerous.
