Notice how Feingold is trying to frame the question in a way that Alito reconstructs?
11:52 Feingold wants to return to questions about Presidential power, and asks if the President can violate a constitutional statute if in bans an inherent constitutional power of the President. Alito says that the constitution trumps a statute, but the situation that Feingold describes fits precisely into Jackson's framework and is the area where the President's powers are at their lowest ebb, and to decide if the President could violate the statute would require an examination of the specific facts.
