I would expect they do, and I'm not entirely against it depending on the circumstances around it and so forth.
To me a 'back door' could range from 'don't fix that bug for a week' to 'push this update to this user' to some absurd 'hey can you add this remote desktop client to your code, the password has to be 1234'.
By no means is it a light thing to do but I do believe there is a range of actions that would constitute a 'back door' to me.
Granted I'm all for more congressional oversight and I'd like to see MUCH more aggressive congressional action.
