Frank's request became reality when he was invited to the White House to mow the Rose Garden lawn and meet the president.
On Friday, the 6th-grader, now 11, got his wish: As Trump looked on, Giaccio donned safety goggles and gardening gloves - then took one item off the White House landscapers' to-do list. Eventually, he turned around and shook Trump's hand. "It's nice to break away and do something a little lighter like that".More news: Brothers featured in "Last Chance U" arrested for murder
"The future of the country right there", Trump said to reporters gathered in the garden.
"Even though I'm only 10, I'd like to show the nation what young people like me are ready for", Sanders said the child wrote.

It is unclear what Giaccio and the president chatted about when Trump strolled over to check on the work.
"Wow, you're doing a great job, Frank", Trump said as he approached the boy, according to a video of the event shared by the White House press office.
