From the September 29 edition of Fox News' On the Record with Brit Hume:
BRIT HUME (HOST): Donald Trump, except for the interviews that he occasionally does on morning shows and as he did last night with Bill O'Reilly, he stopped holding -- seems to have stopped holding news conferences. What's that all about?
BYRON YORK: Far less accessible than he used to be. And basically, I think the Trump view thinks they can perhaps call in a morning show, Fox & Friends and bring up a topic.
HUME: Get the word out.
YORK: Get the word out for the day and kind of set the agenda for the day and don't talk to anybody else. But he's way less accessible than he used to be. And the reason is he used to get himself in trouble by ad-libbing in speeches and by doing media interviews. He's really clamped down on his own speeches. He is much more disciplined now and now he is doing fewer interviews.
