This photograph was taken by Pete Souza on October 30, 2015, during a Halloween celebration at the White House hosted by President Barack Obama and First Lady Michelle Obama for local children and military families. Here, the president and first lady react with delight to a young trick-or-treater dressed as a pope in a miniature popemobile. The previous month, on September 23, 2015, President Obama had welcomed Pope Francis at the White House. It was the third papal visit to the White House, following the visits of Pope John Paul II in 1979, and Pope Benedict XVI in 2008.
