WASHINGTON (CNN) -- The White House Wednesday said it was "puzzled" by a former spokesman's memoir in which he accuses the Bush administration of being mired in propaganda and political spin and at times playing loose with the truth. Former White House spokesman Scott McClellan blasts President Bush and advisers in a new book. In excerpts from a 341-page book to be released Monday, Scott McClellan writes on the war in Iraq that Bush "and his advisers confused the propaganda campaign with the high level of candor and honesty so fundamentally needed to build and then sustain public support during a time of war."
