President Barack Obama along with his family attended an annual holiday concert that will benefit the National Childrens Medical Center on Sunday, December 9th 2012.
This year's "Christmas in Washington" concert included some controversy and something non-traditional: a performance by South Korean "Gangnam Style" rapper Psy.
The controversy arose from the fact that Psyhad actually engaged in anti-American protests eight years ago. He issued an apology for the "inflammatory and inappropriate language" he used in a rap as "part of a deeply emotional reaction to the war in Iraqand the killing of two Korean schoolgirls".
But the controversy didn't affect Obama's attendance. U.S. presidents traditionally attend this charity event, which is in its 31st year.
The First Family also made the time to take some precious pictures with four children dressed as elves who had previously been patients of the Children's National Medical Center in Washington D.C.
The children dressed up as elves greeted the President, First Lady and their two daughters, Sasha and Malia, who showered them with hugs and warm greetings. The earnings from the concert go to benefthe children's hospital, which takes care of some 360,000 patients each year.
Though the event is a yearly tradition, the President seemed particularly taken by this year's batch of elves.
'Ho, ho, ho. You might be the best elves ever,' the president said.
