The problem with your approach is that later on when the investigation either goes no where or the conclusion is not good for Obama all the White House will need to say is "They didn't subpeona us for any records so it not our fault that they got it wrong. They should have asked us. We would have been more than happy to provide them with the information."
So how do they have an investigation as to how the Obama administration decided to make the loan guarantee without even trying to get the information from the White House?
