U.S. President Donald Trump welcomes 11-year-old Frank Giaccio as he cuts the Rose Garden grass at the White House in Washington, U.S., September 15, 2017. Carlos Barria: “Working in Washington, covering politics, I struggle with the rigid and tightly controlled images we’re asked to take. But once in a while I get to witness a natural, unscripted moment. One morning, we were told the White House Pool would gather by the door of the Rose Garden for a photo opportunity. It was unscheduled so I didn’t know what to expect. As it happened, the President was planning to surprise 11-year-old Frank Giaccio, who had written a letter to Trump offering to mow the White House lawn. Giaccio had been invited to work for a day at the White House alongside National Park Service staff. As we waited for Trump, I saw that Giaccio was very focused on this job and not paying much attention to the group of journalists, photographers and cameramen milling around the garden. Suddenly, from the other side of a hedge, wearing his signature, long red tie, President Trump appeared, dropping in as if this were an episode of The Apprentice. He walked towards Giaccio to say hi and pose for a picture. He began shouting to the boy above the noise of the lawnmower, but it was too loud. Giaccio was so focused on his job that he didn’t notice Trump. He walked right past, pushing the machine. Trump paused for a second and walked to the end of the lawn to talk to Giaccio, but again, he didn’t stop mowing. He kept going until his father rushed onto the scene to grab his attention, and he finally stopped to greet Trump. The image of Trump shouting at a kid who is mowing his lawn might have many interpretations in today’s politically polarized United States. But for me it was just a kid who loved what he was doing, to the point he almost appeared to ignore the President.” REUTERS/Carlos Barria/File photo SEARCH “POY STORY” FOR THIS STORY.
