I have the authority to address the threat from Isil, but I believe we are strongest as a nation when the president and Congress work together. So I welcome congressional support for this effort in order to show the world that Americans are united in confronting this danger.

You now have the potential of 200 people deciding who ends up being elected president every single time.

If we want America to stay on the cutting edge, we need young Americans to master the tools and technology that will change the way we do just about everything.

The president and the executive branch are always going to have greater latitude and greater authority when it comes to protecting America because sometimes you just have to respond quickly and not everything that is a danger can be publicized and be subject to open debate, but there have to be some guardrails.

One of the great things about the United States is that when it comes to world affairs, the president obviously is the leader of the Executive Branch, the Commander-in-Chief, the spokesperson for the nation, but the influence and the work that we have is the result not just of the president, it is the result of countless interactions and arrangements and relationships between our military and other militaries, and our diplomats and other diplomats, the intelligence officers and development workers.

The interesting thing about the African-American experience in this country is that we are sort of a mongrel of people. I mean we're all kind of mixed up.

One thing I think we have to do is to make sure that the undocumented workers who are living in America today, that they have to take responsibility. They've got to register, pay a fine, pay their back taxes, learn English and then get on a pathway in which they could have the prospect of being here legally.
