Article: President Barack Obama and First Lady Michelle Obama ended their first trip to India on Monday. The First Couple set off on the ten-day tour of Asia on Friday. Obama's goals for the tour are to improve ties between the US and the region, and to promote economic growth and job creation. The President and his team will return to Washington, D.C. on November 14. The Obamas began their trip in Mumbai, India, the financial and economic center of the country, on November 6. There, they met with government officials, business leaders and school groups. Up first on the schedule was a visit to a memorial at the TajMahal Palace and Tower Hotel.

The five-day religious festival is celebrated each year by Hindus, Sikhs and others. The Obamas spent the holiday visiting with local schoolchildren. On Monday, Michelle Obama joined 15 Indian school girls on a field trip to a museum of Indian craft work. During the tour, the First Lady stressed to the students the importance of education. Most of the children on the trip are the first girls in their families to attend school.
