 During a six-day tour of the African continent in February 2008, President Bush directed Rice, who was with him, to break off to go to Kenya, where Kofi Annan, the former United Nations secretary general, was trying to broker a power-sharing deal.A senior administration official said that the main purpose of Rice's trip would be to step up pressure on Kenya's president, warning him that he risked losing American support if he did not compromise.The message, the official said, was, "If you can't make a deal, you're not going to have good relations."
