No single nation should pick and choose which nations holds nuclear weapons. And that's why I strongly reaffirmed America's commitment to seek a world in which no nations hold nuclear weapons.

America is a strong and resilient country. And I know we will succeed, if we put aside partisanship and politics and work together as one nation.

I know starting careers in troubled times is a challenge, but it is also a privilege. Because it's moments like these that force us to try harder, dig deeper and to discover gifts we never knew we had. To find the greatness that lies within each of us. So don't ever shy away from that endeavor. Don't stop adding to your body of work. I can promise that you will be the better for that continued effort as will be this nation that we all love.

If you were successful, somebody along the line gave you some help. There was a great teacher somewhere in your life.

I would say to people is, that investigation, as it has already been stated, is a marathon and not a sprint. But it is one of great concern to the American people. And so we're committed to keeping people informed.

Look, Americans will go for leadership that makes sense. Our job, you know, as public officials, is not to put our finger in the air. Our job is to listen, and then lead.

In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted, for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things -- some celebrated, but more often men and women obscure in their labor -- who have carried us up the long, rugged path towards prosperity and freedom.
