>> your mom always said learn from your mistakes. learn from your mistakes. president trump's tone-deaf hurricane comments weren't the only time today that he veered away from being presidential. first i want you to listen to his somber tribute to the victims of crash flight 93 in shanksville, pennsylvania, today. >> your tears are not shed alone for they are shared grief with an entire nation. we grieve together for every mother and father, sister and brother, son and daughter who was stolen from us at the twin towers, the pentagon, and here in this pennsylvania field. we honor their sacrifice by pledging to never flinch in the face of evil and to do whatever it takes to keep america safe. [ applause ] >> you know what?
