You know, the truth is that right after 9/11, I had a (flag) pin. Shortly after 9/11, particularly because as we're talking about the Iraq war, that became a substitute for, I think, true patriotism, which is speaking out on issues that are of importance to our national security, I decided I won't wear that pin on my chest.

I'm about to embark on what may be as important as an initiative as anything I do as President, trying to nudge the world in the direction of doing something serious about climate change.

American leadership is not simply a matter of going it alone and bearing all of the burden ourselves.

I've got a pen, and I've got a phone, and I can use that pen to sign executive orders and take executive action. I've got a pen to talk executive actions where congress won't. Where congress isn't acting, I'll act on my own. I have got a pen and I got a phone. And that is all I need.

Too often, we have failed to enforce international norms when it's inconvenient to do so.

When you try to sow the seeds of doubt in people`s minds about the legitimacy of our election, that undermines democracy. Then you`re doing the work of our adversaries for them.

I wish the country had fewer lawyers and more engineers.
