Trump is simply an egomaniacal self-promoter who knows how to use the media to his corrupt ends. I would love to see our professional journalists make a pact in advance of a new conference to demand that Trump answer all legitimate questions. Picture the following hypothetical interchange and its effects:
Trump calls a news conference. In that conference, a journalist asks a legitimate question that Trump does not want to answer. Trump disparages the journalist, and then quickly points to a different journalist to take his or her question. That journalist says: “Mr. President, X asked you a legitimate and important question, and we insist that you answer it.”
Trump angrily disparages that journalist, and points to a third journalist to take a new question. That journalist says: “Mr. President, we repeat: X asked you a legitimate and important question. Answer that question, please. Or this news conference is over.”
Trump explodes in fury, and points to a fourth Journalist. At that point the vast majority of the journalists imply walk away.

Can you imagine that scene? Would it not be delightful? Tell our journalists: “Show that kind of courage.”
