-- President Obama could not resist the chance to tango on his first day in Argentina.
At a State Dinner hosted by Argentine President Mauricio Macri, President Obama and First Lady Michelle Obama were coaxed to the dance floor by professional tango dancers.
Hundreds of guests were entertained by an impromptu performance as the president -- after initially resisting -- sauntered across the dance floor with the professional dancer. Moments later, the First Lady also took a turn at the traditional Argentine dance.
Shocked guests stood to shoot video of the presidential performance.
The state dinner comes at the end of Day One of the Obamas first trip to Argentina. Thursday, the first family travels to Patagonia to hike before flying back to Washington overnight.
