What Jeb Bush Says About George H. W. Bush's New Biography

"I love my dad, he’s a great guy," he said on the trail today.

— -- Jon Meacham's new biography, "Destiny and Power: The American Odyssey of George Herbert Walker Bush," isn't out until next week, but it's already making waves.

George H. W. Bush, 91, writes in the book that Cheney built "his own empire" and asserted too much "hard-line" influence, and Rumsfeld was an "arrogant fellow" and "served the president badly,” as first reported by The New York Times.

Former President George W. Bush responded today that he is "proud to have served with Dick Cheney and Don Rumsfeld."

Rumsfeld wrote in a statement provided to ABC News, "Bush 41 is getting up in years and misjudges Bush 43, who I found made his own decisions. There are hundreds of memos on www.rumsfeld.com that represent advice DoD gave the President.”

George H. W. Bush also worried about the fiery language that he thought his son gave in to.

“I do worry about some of the rhetoric that was out there — some of it his, maybe, and some of it the people around him,” Bush told Meacham of George W. Bush. “Hot rhetoric is pretty easy to get headlines, but it doesn’t necessarily solve the diplomatic problem.”
