Critics of McClellan's book included former White House staffers such as Karl Rove, Dan Bartlett, Ari Fleischer and Mary Matalin. Fleischer and Matalin have claimed that McClellan had not shared similar doubts during his tenure in the White House, and that if he had held such doubts then he ought not to have replaced Fleischer as Press Secretary. McClellan has responded by stating that he, like many other Americans, was inclined to give the administration the "benefit of the doubt" on the necessity of the Iraq War, and did not fully appreciate the circumstances until after leaving the "White House bubble".
