At every step Donald Trump has been - his legitimacy has been questioned.

A free press isn't the enemy of America; it's a big part of why makes America great.

I've reported in countries where leaders not only complain about a critical press, but also try to shut it down, throwing reporters in prison or worse. I've seen my colleagues risk their lives and, with increasing frequency, lose their lives in their pursuit of the truth. We are not about to stop doing our jobs because yet another president is unhappy with what he reads or hears or sees on TV news. There is a reason the founders put freedom of the press in the very first amendment to the Constitution.

The Donald Trump I knew as a young reporter in New York was nothing if not media friendly. And for most of the past Republican primary, he was the most accessible major candidate. No one else was close.

Donald Trump is speaking on behalf of the White House, of the executive branch of the United States. Credibility matters.

Clearly, I regret the email was quoted incorrectly and I regret that it's become a distraction from the story, which still entirely stands. I should have been clearer about the attribution. We updated our story immediately.

The risk is that you've got a vast majority of the electorate saying that they believe the country is going seriously in the wrong direction. But the message here will be hope and optimism and also underscoring the history nature of this, with a woman taking the - a major party nomination for the first time.
