New tell- all book reveals 'jealousy' between Clintons and Obamas

The jealous relationship between Bill Clinton and Hillary Clinton and Barack Obama and Michelle Obama has been revealed in the new book, "Blood Feud," penned by journalist Edward Klein.

According to the book, , Bill and Barack put on a show of unity but privately, the Obamas and Clintons, the two power couples of the Democrat Party, loathe each other, News.com.au reported.

The book also reveals that on most evenings, Michelle and her trusted adviser, Valerie Jarrett, met in a quiet corner of the White House residence and they'd usually open a bottle of Chardonnay, catch up on news about Sasha and Malia, and gossip about people who gave them heartburn.

The former US president would go on to campaign for Obama in 2012, but he felt betrayed when the president seemed to waver when it came to a 2016 endorsement of Hillary. The 52-year-old current US president then attempted to smooth things over with a joint "60 Minutes" interview with Hillary, and later a private dinner for the two couples at the White House.

The two men went back and forth over the subject of where the money for Obama's campaign organization had come from and how to allocate funds for the 2016 presidential election. Bill raised his voice and so did Obama.
