Q. How many neocons does it take to screw in a light bulb?

A. That's an interesting question, one that I'm sure future historians will investigate in detail. Look, let me address this issue up front: I don't know who's been installing light bulbs or who hasn't. That's none of my business. There's a lot of different views, there's a range of views, and a lot of concerns, and we are working to accommodate those concerns. We know at this point that we still have some work to do and we are working very hard to address these issues. We're not making estimates. At this point what you've had are some fairly -- you had some dramatic testimony and comments -- by the way, you can expect people to be ventilating these differing points of views in coming days. Our view is you have to have a resolution that offers a solution. And you're going to have people -- there is sometimes, you'll be surprised to hear, a disparity between comments made in public for domestic audiences around the world, and comments made in private, as well. In short, we don't want to comment on an ongoing investigation.
