Life is too short to dwell on what might have been.

I used to sit on the other end of Pennsylvania Avenue and wonder why the Senate was always going into recess, until in my first year I realized how intense the pressure was.

President Lincoln was trying to convince some people, he used some arguments, convincing other people, he used other arguments. That was a great - I thought a great display of presidential leadership.

We have to work to make sure that our police are using the best training, the best techniques, that they're well prepared to use force only when necessary.

I have pretty thick skin. I've been in the arena a long time, and that means that I am not going to get down with [Donald Trump] and go insult for insult.

I intend to defeat ISIS, to do so in a coalition with majority Muslim nations.
