It wouldn't matter anyway, because it seems one of the tenets of this particular government is: Sure, there's a law. Try and enforce it. Unless I'm mistaken, all the agencies with the power to arrest a member of the Executive branch, lie within the Executive branch itself and they are all controlled, or soon will be controlled, by persons appointed by the President. All of these persons are expected to be more faithful to the current President than to the Constitution. Which means: even if Congress wanted to stop him, there's nothing that it can do to enforce that.
