Sorry that I keep having to interject this way, but we have a full lineup of witnesses. And now you're saying that there's a second tier sitting in the back who may or may not be called. I know nothing about these people. I don't know under what circumstances they are to be called, who's going to call them, or what the line of questioning is.
I thought the steering committee straightened these things out, Mr. Chairman. Can you give me an explanation as to why we have a front line and a second line, and what's going on here?
