I think it was a power struggle between Goss and Negraponte (sp?) and Goss lost out.
The announcement of a successor could be named as early as Monday leads me to believe this was not as "sudden" as it seems.
Then, maybe this is the way Tony Snow wanted it broken and this will be the new style.
I stare at silver linings and have had my eyes glazed before. Hopefully not this time. :-)
There is no suggestion in any way that Porter Goss was involved in the hooker ring. He just was loyal to a friend who was.
