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

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

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

I don't know that the conservatives truly realize this yet, but they are talking about repealing the mandate that says you must have health insurance, and they're talking about repleaing the taxes that help to finance it.

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.

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.

I think that we need to be careful, as reporters and as journalists, not to take the bait and not to get into an endless discussion about issues that are trivial.
