It's not the day in which I grew up, long time ago, where we had three news networks. No cable, no social media, no internet. Where what you see is what you got. We had basically straight journalism. We don't have that anymore.

I've been very lucky to have had a supportive family, a great education, enormous opportunity and challenge.

I think one of the real issues that we're faced with is how we consume news, how the media is perceived, how fake news is gaining a degree of currency without criticism that is dangerous, in my judgement.

We know that weapons, heavy weapons continue to flow across the border from Russia into Ukraine. And we have now, in recent days, indications that Russians - Russian military units themselves have, on occasion, fired into Ukraine.

The United States of America is the leading power in the world. Our friends and our adversaries respect us in large measure because they know that we are steady. We are fact-based. We are serious.

You have to make change.

President Obama has got the most moderate temperament.
