WASHINGTON (Reuters) - President Barack Obama has made headlines for unexpectedly crooning a song or two in public since coming to the White House. Now he can add dancing the tango to his list of hidden talents.

At the end of a state dinner in Buenos Aires with Argentine President Mauricio Macri on Wednesday, Obama and his wife, Michelle, watched with rapt attention as a male and female pair glided and turned in graceful precision across a small patch of open floor in front of their table.
