America is the primary engine of growth in the world and we are the only beacon of free trade left, and open markets.

A crisis allows us the opportunity to dig deep into the reservoirs of our very being, to rise to levels of confidence, strength, and resolve that otherwise we didn't think we possessed. Through adversity, we come face to face with who we really are and what really counts.

It's a tribal state, and it always will be. Whether we like it or not, whenever we withdraw from Afghanistan, whether it's now or years from now, we'll have an incendiary situation. Should we stay and play traffic cop? I don't think that serves our strategic interests.

It's taken a lot of presidents to get us where we are today, a lot of deployments, a lot of wars, a lot engagements. You add them all up.

I think we have to be very sensitive to our need to compete, moving forward, and a lot of that is tied to tax policy.

To be clear. I believe in evolution and trust scientists on global warming. Call me crazy.

I love music, I love all kinds of music, particularly jazz. Jazz is an extension of America. There's no other country in the world that could have produced jazz.
