There seems to be a concerted effort to annihilate the reputation of the previous US president. My impression of the Chilcot Inquiry evidence so far is that it has exposed more of the US failings in the Iraq enterprise than of the British end. Now there are reports like this one that computer technicians for the Obama administration successfully recovered lost emails, which cover a period of 90 significant days of GW Bush's presidency.
The US public will likely be most interested in domestic matters, such as the firing of the US attorney for Arkansas and the outing of the CIA agent Valerie Plame after her husband criticised the Bush administration. However, there may be some interesting additional information on Iraq.
