Why would Obama who co-sponsered a law that keeps politics?

out of the AG office because of the investigations going on of the Bush administration BUT slip a addition to the stimulus bill exempting himself from having to adhere to the law so that he could fire the setting AG because of his investigation into misuse of govern monies by one of Obama largest contributor and the media totally ignores this? Czars are another way to get around the constitution. If Bush abused the constitution in eight years Obama has completely shredded it in less than 6 months everything he has done is against the constitution,
