It has been a little surprising to me, anyway, is to find out through media that there actually have been several chemical attacks recently. Now, with some belief on my part, and I think a lot of people, that we thought we got rid of the chemical weapons with the regime that President Obama and President Putin put in place.

We think we're near energy independence - nothing could be further from the truth. We're in much better shape now, but the price of a barrel of oil is going to be controlled by the Middle East for the next 10, 20, 30 years for sure.

We have to stop the killing. We need to let the refugees - we need to let Syrian citizens go home.

Mr. Chairman, speaking for myself and myself only, it is my personal belief that allowing gays and lesbians to serve openly would be the right thing to do. No matter how I look at this issue, I cannot escape being troubled by the fact that we have in place a policy that forces young men and women to lie about who they are in order to defend their fellow citizens.

We can't kill our way to victory, and no armed force anywhere - no matter how good - can deliver these keys alone. It requires teamwork and cooperation.

The single biggest existential threat that's out there, I think, is cyber.
