The Constitution does not leave to speculation who is to administer the laws enacted by Congress; the President, it says, "shall take Care that the Laws be faithfully executed". . . . The Brady Act effectively transfers this responsibility to thousands of [law enforcement officials] in the 50 States. . . . The power of the President would be subject to reduction, if Congress could act as effectively without the President as with him, by simply requiring state officers to execute its laws.
