Rules for a White House Spokesman: No. 1 is always tell the truth. I've got only one currency, that's the truth. There are 10,000 ways to say "no comment," and I've used 9,999 of them. The second rule is don't be afraid to say, "I don't know." You may look dumb, but if you don't know you can't give them hot air because it always shows on your face.
