I think this is different. I generally feel like executive orders are 1) used to take some kind of affirmative step that the dysfunction in congress is blocking 2) have some level of defensible legal theory. This feels like the opposite. My understanding of the 90 day extension is that it's supposed to be there to allow a deal to close, but there is no evidence I've seen of a deal being worked on so the legal theory seems to be really flimsy. Disregarding a law, while not unprecedented, is not a great sign given some of the incoming administration statements on a ton of other topics.
