The problem here is having the government investigate the government - see a problem? (Remember the Waco investigation for example). You'll never get the whole truth. I think they all have too much dirty laundry and will cover for each other. We need an investigation done by those outside of the government, such as Judicial Watch.
Judicial Watch is not the answer. These are CRIMINAL matters and whoever does the investigation needs the full force of the government to support that investigation. That is the only way we will get to the truth. NO EXCUSES. We MUST expect more of OUR PARTY, otherwise we might as well admit that we only have a ONE PARTY system.
