You are part of the first generation of officers to begin your service in a world where the effects of climate change are so clearly upon us. Climate change will shape how every one of our services plan, operate, train, equip, and protect their infrastructure, today and for the long-term.

The president and the executive branch are always going to have greater latitude and greater authority when it comes to protecting America because sometimes you just have to respond quickly and not everything that is a danger can be publicized and be subject to open debate, but there have to be some guardrails.

Most people who meet my wife quickly conclude that she is remarkable. They are right about this. She is smart, funny and thoroughly charming...

We are one nation under God, and we may call that God different names but we remain one nation.
