[The previous Supreme Court nominees] took a very strict approach. I have taken what I think is a very more pragmatic approach and said, 'If I don't think that's likely to come before the court, I will comment on it,' ... And, again, perhaps that is subject to criticism because it is difficult to draw the line sometimes, but I wanted to be able to share as much as I can with the committee in response to the concerns you and others have expressed, and so I have adopted that approach.
