Each wave of immigrants that have come in have been able to assimilate, integrate and then rise up and become part of this great American Dream.

I was raised by a single mom who had to put herself through school while looking after two kids. And she worked hard every day and made a lot of sacrifices to make sure we got everything we needed. My grandmother, she started off as a secretary in a bank. She never got a college education, even though she was smart as a whip. And she worked her way up to become a vice president of a local bank, but she hit the glass ceiling. She trained people who would end up becoming her bosses during the course of her career.

My greatest hope is to be able to pass the same dreams and hopes and vision that I've been able to enjoy in my life, on to the next generation. Not just for my children - because with a mother like Michelle, my kids are going to be great - but for all children. There are too many children in this country for whom the American dream is so distant and the odds against them are so daunting.

[Our troops in Iraq and Afganistan] does give us the ability to make sure that we are strengthening those folk who are interested in building up their countries rather than destroying them, and doing so in a way that is sustainable and doesn't put a constant burden on the amazing men and women that we've got in uniform.

We are now at a point where because we in fact have been successful at stopping a number of plots, a threat has evolved. We do see these lone-wolf actors. We do see these encouragements for troubled individuals to pick up a gun and act out of this ideology.

This is why the anti-discrimination principle being enforced is important. Because it won't stop if some of the underlying biases aren't challenged and surfaced. And that in and of itself creates backlash and denial. This is what I mean when I say better is hard.

We as a country have to do some soul-searching.
