VIDEO: US President Barack Obama arrives in for visit

It is his first visit to his father's homeland as President of the United States.

Obama returns to Kenya, reunites with father's family

The president spent the evening reuniting with his Kenyan family, including his elderly step-grandmother who made the trip to the capital of Nairobi from her rural village. U.S. and Kenyan flags lined the main road from Nairobi's airport, and billboards heralding Obama's trip dotted the city.

"I don't think that Kenyans think of Obama as African-American. They think of him as Kenyan-American," said EJ Hogendoorn, deputy program director for Africa at the International Crisis Group.
