I'm not a teacher.
I found the following in "Comments by President On His Choice of Justice" in the New York Times:
George Bush senior: "No, and a lot of other things too. I believe in the separation of powers. I happen to think that there's been many many things that trouble me - encroachment of micromanagement by the United States Congress on the Presidency. But I haven't asked this able judge about those things."
I would post a link, but I have not enough posts to have that privilege.
