Mr. [Donald] Trump, for five years, you perpetuated a false claim that the nation's first black president was not a natural-born citizen. You questioned his legitimacy. In the last couple of weeks, you acknowledged what most Americans have accepted for years: The president was born in the United States.

You never know what doors are going to open up and why they are going to open up. You've got to be ready to walk through them.

I think we're more relevant than ever because it is such a noisy environment out there. What's a journalist now? It's anybody with a way to get information out and you're sitting there with your smartphone in front of you. That's what we're up against now. There's a lot of unfiltered information. Some of it is accurate, some of it way off base. We're that safe port in the storm.

One of the most important skills at [reporting] is not so much what comes out of your mouth but what you hear. To listen.
