It has been widely reported that Bush will now "answer all the questions of a federal commission investigating the Sept. 11 attacks" according to Scott McClellan.

It is likely that Bush and Cheney will be asked about pre-9/11 intelligence. Clinton and Gore are going to testify in private, while Sandy Berger will testify in public.

This should be really interesting. Stay tuned!

MAJOR UPDATE: CAP has an overview of what is publicly known about pre-9/11 intelligence and warnings It seems very good. I don't have the time to fact check everything there, but the links all work. :)
