Frank Giaccio, 11, mowed the White House lawn on Friday after sending President Donald Trump a letter saying he’d complete the task “at no charge.”

White House press secretary Sarah Huckabee Sanders read Frank’s letter during a daily briefing in August.

“You’re free to pick whatever you want: power mower, push mower and weed whacker,” wrote Frank, who lives in Falls Church, Virginia.

Under the supervision of park service employees, Frank used a push mower to mow the grass in the Rose Garden. He was so focused on the task that he didn’t even stop when Trump came out to greet him.

Trump gave some encouragement and a high-five for the hard work, telling Frank he was doing a “great job.”

“Maybe he’ll be president,” Trump said of Frank, who aspires to become a Navy SEAL when he grows up.
