The clip above speaks for itself. There's nothing to add.
And here's the quote of the day, from January 2001, via ABC's Jake Tapper:
"The proof in the pudding is looking at the treatment of the other Bush nominees," Obama said. "I mean for the most part, I for example do not agree with a missile defense system, but I don't think that soon-to-be-Secretary Rumsfeld is in any way out of the mainstream of American political life. And I would argue that the same would be true for the vast majority of the Bush nominees, and I give him credit for that."
