Administrative Procedures and Trump

This ThinkProgress post represents one of the hurdles for the Trump revolution:  simply put, once a regulation is in place, the bureaucracy has to use the Administrative Procedure Act to revise/change/revoke it, including cost/benefit analysis and consideration of public comment.  (There are exceptions to this, of course, and I'm specifying "the bureaucracy" since Congress can change the game, but it's a good general rule.)  In the case of the Clean Water Rule, a judge has found EPA and Corps of Engineers to be rushing too fast (because it's not a simple case, other court cases involved) in their analysis.
