Exactly...likely with more to follow. While Congress can “undo” Executive Orders, it takes agreement in both Houses and a will to get it done, which is unlikely. Even if they do rescind it, the damage will have already been done. Not good...
The next election is a little over a year away. The next President can undo what this one has done with a new set of executive orders. The saving grace in this is that government moves so slowly. Had he done this day one of his administration the damage would have been far worse.
