I would describe it as him losing patience with a reporter that won't yield her time. Trump is just is more likely to answer a question badly than he is to run from it. The dude is a narcissist. Viewing it from that lens, he is more annoyed at being disrespected than he is at the question being asked, and that is what played out.

He tried moving on from her for about 15 seconds after answering he question. He's already getting frustrated because she won't quit asking him the same question, and he asks another reporter to go. Then she comes out with a new question, and the reporter he's calling on won't ask him anything new, so he leaves. If she had led with the question about veteran's choice, and he was ducking it from the start, I could see the narrative that was presented in the original post. However the way it played out looked more like Trump just bailing due to a hostile press. Again, I can see how some one might draw the conclusion that was drawn above, but I don't think it's the most reasonable conclusion.
