Tonight, let us think back to the sense of unity that prevailed on 9/11.

The role of citizen in our democracy does not end with your vote.

Think about it: Iran, Cuba, Venezuela - these countries are tiny compared to the Soviet Union. They don't pose a serious threat to us the way the Soviet Union posed a threat to us.

If you don't have good people, and you don't have a good process and you don't have, at some level, the basic reverence for [presidential] office, and an understanding of the incredible responsibilities and obligations, then, I think you can get into trouble.

With respect to Russia, my principal approach to Russia has been constant since I first came into office. Russia is an important country. It is a military superpower. It has influence in the region and it has influence around the world.

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 in fact the Republicans make some modifications [of Obamacare], some of which I may have been seeking previously, but they wouldn't cooperate because they didn't wanna make the system work, and re-label it as Trumpcare, I'm fine with that.
