President and Michelle Obama will leave Washington on Wednesday for a week-long trip to three African nations, focusing on economic development, democracy building and private sector investment.

Among the highlights for the president will be bilateral meetings with the leaders of Senegal, South Africa and Tanzania, visits to Senegal's supreme court and a power plant in Tanzania, tours of a slave museum in Gorree Island and the site of the prison where Nelson Mandela was held for two decades on Robben Island. Obama also will tour a community center with Archbishop Desmond Tutu in Cape Town.
