Well, I haven't seen the Larry King episode referred to, but CNN's web site had this article regarding the Woodward interview. It doesn't address the "oil price" issue, but does have some information regarding other areas of dispute in Woodward's book, such as when Powel was informed of the decision to go to war and when Bandar new.
http://www.cnn.com/2004/ALLPOLITICS/04/20/woodward.book/Sounds to me like many of the assertions Woodward made, those being disputed by the administration, may have been a question of misinterpretation. For instance, Bandar was apparently
briefed on the war plan (which Powel had already reviewed numerous times), but Bandar himself said he did not know a decision had been made to proceed until the night before the start of military operations. Woodward may have taken the statement, "Bandar was briefed on the
war plan on January 11 (well before the administration says the President made a final decision, and thus before Powel would have been told), and heard "Bandar was briefed on the
war decision on January 11." Just a thought.
