lawfag here
the volume complexity and absurdity of the federal law is so enourmous there is no lawfag or anyone else that can answer this question in good faith
yes there are many authorities granted to POTUS
there are also many restrictions
there are also many DS judges
i am certain POTUS had an array of specialists and lawyers look and every aspect as best as possible before deciding - this alone is a very large task
so we will have to wait and see
