U.S. Presidents To Attend Mandela Memorial

(Johannesburg, S. Africa) -- Every living American president except one will attend tomorrow's memorial for former South African President Nelson Mandela. President Obama is due to leave the White House later on this morning. He'll be joined by former presidents George W. Bush, Bill Clinton and Jimmy Carter, along with dozens of other heads of state at the service in Johannesburg. The only U.S. president not going is 89-year-old George H.W. Bush.

President Obama and First Lady Michelle Obama are on board Air Force One heading to South Africa to attend a memorial service honoring the late Nelson Mandela. Joining the Obamas on the three-day trip are former President George W. Bush, former First Lady Laura Bush, and former Secretary of State Hillary Clinton. Former presidents Bill Clinton and Jimmy Carter are traveling to South Africa separately. The American contingent will gather with more than 70 world leaders for a ceremony Tuesday at Johannesburg's Soccer City stadium. South Africa's first black president died last Thursday at the age of 95.
