Trump chose to call on Turx, and the question was such a softball that it could have only been “nicer” to the point of ridiculousness, like asking, “Mr. President, given how extremely awesome you are, how do you not make other people in the room feel so lowly in your presence?” Had the president just responded something even simple such as, “I think anti-Semitic acts are terrible”, there would have been no story.
You shouldn’t be so surprised that Trump reacted the way he did. That’s who he is.
