“The president took a deep breath and steeled himself, and went into the first classroom. And what happened next I’ll never forget.

Person after person received an engulfing hug from our commander in chief. He’d say, “Tell me about your son. . . . Tell me about your daughter,” and then hold pictures of the lost beloved as their parents described favorite foods, television shows, and the sound of their laughter. For the younger siblings of those who had passed away—many of them two, three, or four years old, too young to understand it all—the president would grab them and toss them, laughing, up into the air, and then hand them a box of White House M&M’s, which were always kept close at hand. In each room, I saw his eyes water, but he did not break.

And then the entire scene would repeat—for hours. Over and over and over again, through well over a hundred relatives of the fallen, each one equally broken, wrecked by the loss. After each classroom, we would go back into those fluorescent hallways and walk through the names of the coming families, and then the president would dive back in, like a soldier returning to a tour of duty in a worthy but wearing war. We spent what felt like a lifetime in those classrooms, and every single person received the same tender treatment. The same hugs. The same looks, directly in their eyes. The same sincere offer of support and prayer.”
