My reading of the article is that the administration, Ms. Rice in particular, who as far as I know is not a scientist, pressured the EPA to remove language from the EPA's draft.

While its quite possible and I think even likely that Bush himself does not take an interest in this sort of thing, he is President CEO. He himself endorsed legislation that would make CEO's legally liable for the truth of their audit statements. I can only assume that he feels CEO's of companys ought to be more directly responsible than Presidents.
