The Bushes, according to multiple reports, accepted an invitation to accompany the Obamas on Air Force One. It’s unclear whether the Clintons will be flying with them. 

Mandela, the former South African president and anti-apartheid leader, died late Thursday at age 95. He had suffered from poor health for a year.

Soon after the news broke, Obama delivered a statement from the White House in which he reflected on Mandela’s life, and called him an inspiration.

“Let us pause and give thanks for the fact that Nelson Mandela lived — a man who took history in his hands, and bent the arc of the moral universe toward justice."

Obama has spoken to current South African President Jacob Zumas and Mandela's widow Graca Machel by phone to express his condolences.
