Obama, who became the first black US president, is the son of a black father from Kenya and a white mother from Kansas.
The US president is visiting with a mission to strengthen US security and economic ties, but his personal connection to his father’s birthplace will dominate a trip viewed as a native son’s return to his home.
He will hold bilateral talks and dine with President Uhuru Kenyatta, and co-host the 6th Global Entrepreneurship Summit.
He will also give public addresses at Kenyatta University and Safaricom Stadium Kasarani.
Obama departed for Kenya on Thursday, his first trip to his father’s homeland as US president, kicking off a swing through Africa that includes a stop in Ethiopia.
He boarded Air Force One from Joint Base Andrews, Maryland and made a stop over at Ramstein Air Force Base in Germany.
