Hello, Buenos Aires: The Obamas do the tango

The president and first lady Michelle Obama were attending a state dinner in the Argentine capital when they were pulled abruptly onto the dance floor on by a pair of dancers hired to provide the entertainment.

At first, the woman in the shimmering gold dress seemed to content to twirl with her partner, but then she made a beeline for the president and beckoned him to the floor.

Mrs. Obama got in on the action, too, twisting back and forth with the black-clad male dancer.

After the deadly bombings in Brussels this week, critics have argued the president should have toned down his trip, which also included a stop in Cuba, where he attended a baseball game.
