Former President Barack Obama's journey to French Polynesia was undertaken so he could write his memoir.

Obama arrived at a luxury resort frequented by Hollywood stars in mid-March, though it was unknown at the time what he was doing there.

The Washington Post reported Sunday that Obama is writing his White House memoir during his extended stay at the eco-friendly resort in French Polynesia's atoll of Tetiaroa.

Bidding for the former president and first lady Michelle Obama's book rights surpassed $60 million.
