But what I would say to my successor is that it is important not just to shoot but to aim. And it is important, in this seat, to make sure that you're making your best judgments based on data, intelligence, the information that's coming from your commanders and folks on the ground and you're not being swayed by politics.

I can't really characterize any country, except to say that we work well with a number of our foreign counterparts.

Our intelligence communities spend a lot of time and effort gathering a lot of strands and a lot of data [on Russian hacking]. There are times where they're very cautious and they say, "We think this is what happened, but we're not certain."

I believe in returning the nation's wealth to its rightful owners.

Having a tax code that rewards companies that are shipping jobs overseas instead of companies that are investing here in the United States, that will not make us more competitive.

I'm a Christian by choice.

I think it is important first of all that the president of the United States underscores our commitment to partnering with countries around the world, even though we're not intimidated by terrorist organisations.
