We did not come to fear the future. We came here to shape it.

Marco Rubio is one of those people. How does that work? How can you call him a con artist and dangerous, and object to all the controversial things he says, and then say, but I`m still going to vote for him? Come on, man.

It is that fundamental belief, it is that fundamental belief, I am my brother’s keeper, I am my sister’s keeper that makes this country work. It’s what allows us to pursue our individual dreams and yet still come together as one American family. E pluribus unum. Out of many, one.

One of the challenges over the last decade is America has done experiments in nation building in places like Iraq and Afghanistan and we've neglected, for example, developing our own economy, our own energy sectors, our own education system. And it's very hard for us to project leadership around the world when we're not doing what we need to do.

It's important to recognize that you can't have 100 percent security and also then have 100 percent privacy and zero inconvenience.

I want to control our own energy by developing oil and natural gas but also the energy sources of the future.

This is a core principle of my presidency - if you threaten America, you will find no safe haven.
