Undocumented workers can't report if they're not being paid overtime, or if their health and safety laws are being violated, of if they're not getting the minimum wage. And so a lot of times companies prefer to hire them in order to take advantage of them. We've got to crack down on those employers.

We have to stand up for these issues when it's tough, and that's what I've done. I did it when I was in the state legislature, sponsoring the Illinois version of the DREAM Act, so that children who were brought here through no fault of their own are able to go to college, because we actually want well-educated kids in our country who are able to succeed and become part of this economy and part of the American dream.

And terrorists who seek to harm our citizens will feel the long arm of American justice.

To sustain a governing majority, that requires an ability for Republicans and Democrats to find some common ground. And right now, the structure of the system is such where it makes it really hard for people to work together.

I do have an obligation to make sure that I am following some of the rules. I can't simply ignore laws that are out there.

What I remember thinking at that point, having gone through both the ups and downs of my first four years, and seeing the sea of people was, "What a remarkable country this is and how lucky am I that we live in a place where the son of a single mom, not born into any kind of fame or fortune, in a pretty remote state somehow can end up be in a position to - to make a difference."

In recent years, we've become enamored with our own past success. Lulled into complacency by the glitter of our own achievements. We've become accustomed to the title of Military Superpower, forgetting the qualities that got us there. We've become accustomed to our economic dominance in the world, forgetting that it wasn't reckless deals and get rich quick schemes that got us where we are, but hard work and smart ideas, quality products and wise investments.
