If there was an invitation to participate, I would consider it, but, you heard me mention the Constitution a few times this morning. Under the Constitution, we have three co-equal branches of government, and any invitation to be directed to me, I would have to reflect on the unique role I was serving in as vice president. It would be unprecedented in history for a vice president to be summoned to testify on Capitol Hill. But, as I said, I don't want to pre-judge, so if there's ever any formal invitation rendered to us, we would give it due consideration.
