Michelle Obama, Jill Biden make surprise visit to Haiti

First Lady Michelle Obama kicked off her first foreign trip without her husband on Tuesday by making an unexpected stop in the earthquake ravaged city of Port-au-Prince, Haiti.

Obama took a helicopter tour of the city, accompanied by Dr. Jill Biden. Monday marked the three-month anniversary of the magnitude 7.0 earthquake that leveled much of the island.

The White House didn't tell reporters about the stop until the plane landed. The first lady is due in Mexico City late Tuesday afternoon for the start of a three day visit.

According to a statement from the Obama administration, the stop in Haiti was intended "to underscore to the Haitian ... the enduring U.S. commitment to help Haiti recover ... especially as we enter the rainy and hurricane seasons."
