Barack and Michelle Obama welcomed one of the world's most powerful women, German Chancellor Angela Merkel, to the White House tonight for a state dinner under the stars. Joined by her husband, Joachim Sauer, Merkel became the first European leader to get the American state dinner treatment since Obama came to office in 2009. Tonight, guests will enjoy the capital's late-Spring heat, dining outside in the Rose Garden. They'll also be treated to at least one German specialty: apple strudel for dessert! On the heels of last month's state visit to England, America's first couple have recently enjoyed quite a few elegant date nights. See their latest now.
