One of the unwritten rules in a presidential news conference is that he'll answer questions. If he chooses not to, there's not much you can do about it other than make yourself look like an idiot screaming, which to me is counterproductive.

I certainly don't think Donald Trump suggesting violence in any way.

I just think we as consumers of information media must be very clear what it is we are consuming. Whether we are choosing to get our information by listening to people fight about it. Or whether we're choosing to get it by listening to the facts or watching the facts as they're laid out and then reaching our own conclusions. It's very different ways of info gathering, but it's not all journalism.

I spent my career trying to speak to the broadest possible audience whether it's in print or whether it's in television.

Don't count out other amazing programming like Frontline. You will still find more hours of in-depth news programming, investigative journalism and analysis on PBS than on any other outlet.

In the media universe we're in, where there are people screaming on one end, there is no problem at all with having a little bit of extra politeness.
