Immigration is the most difficult issue I've ever dealt with, and I've dealt with some tough issues: drones, gays in the military, WikiLeaks, Guantanamo. But immigration is hardest because there are so few people willing to talk and build consensus. Everybody's firmly made up their mind. It's a polarized issue.

Under well-settled legal principles, lethal force against a valid military objective, in an armed conflict, is consistent with the law of war and does not, by definition, constitute an 'assassination.'

In my view, targeted lethal force is at its least controversial when it is on its strongest, most traditional legal foundation. The essential mission of the U.S. military is to capture or kill an enemy. Armies have been doing this for thousands of years. As part of a congressionally authorized armed conflict, the foundation is even stronger.

ISIL, AQ, now have the ability to literally reach into our homeland through social media, through the Internet, to recruit and inspire. It makes for a more complicated homeland security environment. And so it requires a whole of government approach, not just military and law enforcement, homeland security, aviation security, and the like.

I don't need anyone to look after me financially and, while it's hard to trust that a man loves you for the right reasons, you have to take a leap of faith.

We get the papers: I prefer broadsheets because I had the fear of God put into me by the tabloids and, though I'm very much over it, I still don't really like to read them. It's a destructive vernacular that makes me angry and scared, and it is all sensationalist onomatopoeia and alliteration.

It is the easiest thing in the world to become a Christian - ten thousand times easier than it is to hold out unrepenting against the motives which God presents to the mind, to induce it to forsake its evil thoughts and turn unto Him.
