> And, by the way, where in the Constitution does it say that the President of the United States is the Chief Executive Officer for the United States Government?

Art 2, Sec 1: "The executive Power shall be vested in a President of the United States of America."

That means *all* of it. If it counts as executive power, the President has it and no one else. Unless there's been a lawful delegation.

Just as the Congress is the legislative branch, the person of the President is the executive branch. Congress can pass laws about how the executive branch operates--- agencies and so forth. But they cannot interfere with the President's prerogatives as the executive, which plainly include coming up with increased security procedures.

I agree with you that this is bad policy. But it's all certainly legal.
