Thomas R. Carper: “We need a leader at the IRS who's been confirmed by the U.S. Senate.”

I would say there is a lesson here for both of us, and one of those is to make clear I am always ready to take your calls, your meeting, whatever you want and engage.

People ask me what I am proudest of in my life, and I always say, raising three boys, with a big assist from their mom.

You and our colleagues have heard me invoke in this room more times than I can count the Golden Rule: Treat other people the way I want to be treated.

We help make the rules for the country, and we do not do this by ourselves.
