I voted against the war in Iraq. I voted against the first Gulf War. I think war is the last resort - the last option of a great military power like us. I think that we need to focus on building coalitions. Yes, ISIS must be destroyed. But it should be destroyed by a coalition of Muslim nations on the ground with the support of the United States and the other major powers in the air and in training the troops there.

Wish we could, and allow the Taliban or anybody else to reclaim that country. But what we must do is some progress in Iraq, where finally the Iraqi army, which has not been a particularly effective fighting force, retook Ramadi.

Hillary Clinton is a person who has enormous - I have enormous respect for, has a very distinguished career.

At a time when the Post Office is losing substantial revenue from the instantaneous flow of information by email and on the Internet, slowing mail service is a recipe for disaster.

When Hillary Clinton ran against Senator [Barack] Obama she thought him naive because he thought it was a good idea to talk to our enemies. I think those are exactly the people you have to talk to and you have to negotiate with.

We have to transform our energy system.

It's better to show up than to give up.
