Cheney was angered over Rumsfeld’s ouster.

The Plank’s Isaac Chotiner finds this interesting revelation from Stephen Hayes’ Cheney biography. Hayes describes the events as Cheney’s staffers were preparing him for an appearance on Fox News Sunday:

An aide fired one tough question after another at the vice president. Then: Did you agree with President Bush’s decision to replace Donald Rumsfeld as secretary of defense?

“Absolutely not,” Cheney replied without elaborating. His answer surprised the small group with him, but it was the answer he was determined to give if Wallace asked, even at the risk of angering his boss. But the story was a month old, and Wallace never asked the question.
