Before flagging, please consider how this act has not been invoked since WW2. Therefore it is a novel and worthy of discussion, regardless of how "not technology related" it is.
I mean, it trivially fits a number of them but a really big one is 'repetition'. Various political and other not-entirely-HN-on-topic stories end up on the front page and have threads but these are exceptions for particularly unusual or big ones. An administration that engages in daily shitposting-through-executive-order gets a couple of these for novelty but the novelty has long worn off - you'd have to fill HN with them if they all counted as exceptional.
Of course, if you think this one deserves special treatment, the thing to do is email hn@ycombinator.com and ask for flags to be taken off. I think in this case it's a little uphill (as another toplevel comment points out - the news has already overtaken this thing) and you'd probably need to find some sort of third party reporting rather than the government press release.
