The news media has lost its way. The current paradigm is that reporters need to hold interviewees accountable for what they say, and that their job is to “push back” against what they perceive to be disingenuous statements. I think that’s wrong and counter-productive.
The role of the reporter is never to argue with the interviewee. To do so, especially with a personality like that of Trump, who is basically a child, devolves the interview into a power struggle that no one can win (except Trump in this case who thrives on the perception that he is attacking the press.)
This was particularly apparent in the debates when moderators were castigated for not arguing with the candidates about their statements. Those who did were celebrated as being “good” moderators. Aside from the fact they weren’t moderators at all, the debates often became mere pissing contests between the candidates and the panelists. Unfortunately, the competition among reporters has forced them to compete with others to stand out among the crowd and they seem to think only by creating a lot of noise can they do so.
Much better to ask the question and let the answer stand, however unsatisfactory. Let the audience decide and the reporters can write about the validity of the response later when they have had time to research and reflect on the proper response, collecting the facts. For example, ask Trump why he has not released his tax forms. He can answer, next question. To argue about whether he should or not reduces the amount of time available for other questions and places the reporter in the stance of adversary (a role for the editorial pages) rather than reporter. A press conference is not a debate nor power struggle. It should be a time for reporters to ask intelligent and probing questions and let their editors and readers decide the veracity of the answers.
