I mean, if that's what the law allows, then sure, that would be a valid thing for the next president to do. It would be bad for the country to do so, but plenty of things that are bad for the country are legal for the government to do.

We'd have no choice but to accept that as a legitimate use of funding discretion, assuming that actually is the case (I don't know the law related to this, so I can't say). We can be upset at that decision, but we'd still have to accept it as legitimate.
