When did Bush learn about Abu Ghraib?

Since the Abu Ghraib scandal broke, the Bush administration has tried to paint the whole thing as the work of a few bad apples - despite Defense Secretary Donald Rumsfeld's approval of many of the controversial interrogation methods at the heart of the scandal, including the use of forced nudity, blackout hoods, forced standing, and threats of German Shepherd attacks (designed to exploit what one memo called the "Arab fear of dogs").

Furthermore, although Rumsfeld never officially authorized it as an interrogation method in the way he did the aforementioned techniques, there is strong evidence that the photographs of forced homosexual activity at Abu Ghraib were part of a plan to blackmail deeply religious Muslim prisoners through sexual humiliation (see the post "Conservatives for gay sexual abuse").

Now, Seymour Hersh, the New Yorker reporter who helped break the scandal, has a new piece on when Bush learned of the situation, and what he did (and/or didn't do) about it. The Washington Post article provides a good overview of the longer New Yorker article.
