Former US President Barack Obama arrived in Kenya on Sunday for a quick family visit before he heads to South Africa to attend Nelson Mandela's birthday tribute. This is his first trip to the country of his father's birth since leaving office. Obama met Kenyan President Uhuru Kenyatta, opposition leader Raila Odinga and other top officials after his arrival. On Monday, he'll attend the inauguration of a sports and vocational center founded by his sister, Auma Obama.
