It appears that there may finally be some progress on investigation into Bush’s warrantless wiretapping program. There is an unclassified summary written by five inspectors general, according to the Washington Post.

The inspectors general from the Departments of Justice and Defense, as well as the CIA, the NSA and the office of the Director of National Intelligence, said they reviewed thousands of documents and interviewed more than 200 people in connection with the report, including Bush era officials John Negroponte, who served as director of national intelligence, National Security Agency Director Michael V. Hayden, Secretary of Defense Donald Rumsfeld and Attorney General Alberto Gonzales.

But other key figures such as Bush White House Chief of Staff Andrew Card, former Attorney General John D. Ashcroft and former CIA director George Tenet declined interview requests, investigators said. The inspectors general lack the authority to compel them to talk.
