Jim Acosta has done this many times. If he was really interested in answers he would continually modify his approach until he got what he wanted. But he's not really interested in answers so much as making a show of Trump not answering his questions. Case in point, I have no clue what he was asking, all of the stories have been about the reporter. Contrast with the Axios interview on HBO this week, where the interviewers discussed trying something different and effectively got a unique Trump interview.
