President Obama will be joined by George W. Bush at a wreath laying ceremony Tuesday morning at the site of the 1998 embassy bombing in Dar es Salaam, Tanzania.
The two are not expected to make remarks, according to White House Press Secretary Jay Carney.
Bush is traveling in Zambia and Tanzania to promote his Pink Ribbon Red Ribbon initiative, which seeks to fight cervical and breast cancer. Mrs. Bush and Mrs. Obama will also appear together at a conference on African Women in Dar es Salaam organized by the George W. Bush Institute.
Obama arrived in Tanzania Monday morning. The presence of Obama and his predecessor as president in Tanzania at the same time is coincidental, officials said.
