Never waste a good crisis...Don't waste it when it can have a very positive impact on climate change and energy security.

I'm one of those people who thinks that changing one's hair is the only part of the body that you can change at will.

I do. You know, I made a mistake using a private e- mail.

I think that, given the threat that ISIS poses to the region and beyond, as we have sadly seen in our own country, it is important to keep the Iraqi army on a path where they can actually take back territory, to work with the Sunni tribes in Anbar province and elsewhere so that their fighters can be also deployed, to work with the Kurds to provide them the support, but they're doing the fighting. We're doing the support and enabling.

It is often when night looks darkest, it is often before the fever breaks that one senses the gathering momentum for change; when one feels that resurrection of hope in the midst of despair and apathy.

I believe we have to take this step by step to try to reign in Iranian aggression, their support for terrorism and the other bad behavior that can come back and haunt us.

The children-my own and other people's-became the passion of my personal and professional life.
