I noticed that President Trump was in a press conference in which he was insulted. He had discussed taxes. Then as he was walking out one of the reporters yelled and screamed at him at him, "Why did you not pay any taxes?!!!" Besides the fact  that that is an obvious lie, what was the most interesting thing was that President Trump did not answer. He just kept on walking.

The reminded me of the LeM of Rav Nahman of Breslov עיקר התשובה שישמע בזיונו יידום וישתוק "The main repentance is to hear your insult and to be quiet and not answer." 

I doubt if President Trump learns the LeM of Rav Nahman, but still it is interesting that he must understand this fact intuitively.
