The difference here is how we're thinking of "the law".

Obviously, if what you're looking at is the text of the legislation, it's as clear as could be.

But "the law" consists of quite a bit more than that. It has never been challenged in court before so it's still an open question whether it's even constitutional. If their interpretation is that it isn't... then a court would need to weigh in before they released anything.

Additionally, it's possible for Congress to exercise a power that it has - but do so in an impermissible way. More than one court has ruled against Trump one things that he had the power to do... but didn't do it correctly. Again, a court would have to rule on that.

Getting to an answer could take months or even years. Going through NY is likely to be easier and faster.
