At the White House, young children of staff members -accompanied by their parents- arrived in costume to collect Halloween candy from President Donald Trump and the First Lady.
The couple, who chose not to wear costumes, greeted families, posed for photos and signed autographs in front of the decorated White House.
The light-hearted celebration came as Trump returned from a week of high-level meetings in Asia, including talks with Chinese President Xi Jinping on trade and tariffs.
