No, but friends of NSA like Mike Rogers have said in public that "he's not worried about this spying, because NSA doesn't spy on him, because he's not a 'bad guy'".

Of course, I don't think even he believes that, because he knows exactly what NSA is doing, but it's good to know for a fact that NSA does spy on US Congress, too. Maybe this information will make the undecided politicians to take the right side.
