US President Barack Obama’s family will not accompany him on his tour, which begins on Friday.
According to the Office of the President, senior adviser Ruth Kagia, Mrs Michelle Obama and her daughters, Malia and Sasha, will not be with Mr Obama during his first visit to Kenya as head of state.
State House did not give the reasons for their absence. One reason could be that the tour coincides with the beginning of the school term in the US and the girls have to attend lessons.
The President will, instead, be joined by National Security adviser Susan Rice, Commerce Secretary Penny Pritzker and other senior US Government officials.
President Obama is expected to arrive in Nairobi tomorrow evening. He will be accompanied by journalists, secretaries, advisers and secret service agents.
“This event will bring the best in the industry together. More than 3,000 very important people will be coming to Nairobi and this is something we will remember forever,” Ms Kagia told the Nation.
